    Leaves much to be desired


    I bought this keyboard a few years ago and it's been my main one all this time. I bought it because of the height platform it came with that raises the wrists up to a very ergonomically comfortable level. Unfortunately, this also makes the keyboard take up a huge footprint and will not fit on the keyboard drawer in a lot of desks. Thus, I've taken it off and don't use it. The keyboard is a standard Win95 format which includes several media buttons for extra functionality. I personally am not a big fan of them except in the case of audio controls, which do not function since I use iTunes instead of Windows Media Player. Value for Price There are far better keyboards out there for the price you'll pay for this one. The ergonomic shape, however, is great if you're really concerned about ergonomics and wrist injuries. Compatibility Works "out of the box" in Windows of course. Haven't tried it on a Mac. It is only compatible with Windows Media Player. It will not control iTunes. Anyone with an iPod will find the audio controls useless. Design The ergonomics and shape of the keyboard are, like I mentioned, very well designed for the human hand. I write quite a bit and do not experience any wrist fatigue. However, that's about the only good I can say about it. My first grip is the audio controls. Only Volume Up/Down and Play/Pause are present. No next track or previous track buttons. Come on Microsoft! I use the Next and previous track buttons way more than the Play/Pause button, but since it doesn't work with iTunes anyway that makes it a moot point. The other problem I have with the design is that its extremely LOUD. It reminds me of those old clickety-clackety keyboards from the 80's. Plus, the space bar's curved shape makes it difficult to press down. I have to slam it hard with my thumb every time. If it were a standard keyboard with no curved shape and platform it would be a carpal tunnel machine without a doubt. My wife's computer is in the same room and she can barely stand it when I'm typing because it's so loud and annoying. Ease of Use Hey, it's a keyboard. You type on it and words appear on the screen. It's not rocket science. All the keys are in the right place and the only issue would be if you've never typed on an ergonomic keyboard before. I regularly switch from a standard keyboard at work to this one and I never even notice. So in short it may take some getting used to, but it's not that bad. Overall Overall this keyboard is NOT worth the money. Next time I'm probably going to go with Logitech or some other brand that has full audio controls and doesn't sound like a train going over tracks when I type on it.

    Microsoft Natural Ergonomic Keyboard 4000


    Other than the ergonomic shape and key layout, this keyboard offers absolutely no notable features as compared to many much less expensive keyboards. I feel that it is overpriced by $20 to $30 except, sometimes, when it is on sale, and that Microsoft is, as usual, merely taking advantage of the Microsoft name in addition, in this case, to the terms "natural" and "ergonomic", in order to charge a non-value-based price. The "plug and playability" is convenient, as the keyboard will function adequately, at least on a Windows based system, without even installing the accompanying software. I would, however, recommend installing the software in order to achieve full functionality. There are, however two major physical defects. First, the letters and symbols on the keys are decals and they wear quickly. As this is the only decent keyboard my local store has for under $90 or so, I have now had 3 of them, and in each case I start losing key labels within less than 3 weeks, with the letter "E" the first to go and the "A" following closely behind. Second, there is something about the physical layout of the keys that causes me to hit Cap Lock, instead of Shift, all too often. This creates a lot of extra work when, as usually happens, I do not notice the problem until after a couple paragraphs or so of typing, especially in applications where I cannot do a simple mass change of case as can be done in Word. While I have this problem occasionally with other keyboards, both "regular" and "ergonomic", it is a once in a while thing. With this keyboard, it is a constant continuing problem. It also happens, with a lesser frequency but still more so than on any other keyboard, with the Control key, which REALLY messes up whatever it is I am doing at the time and often causes loss of whatever I had been inputting. This keyboard is in serious need of much more durable key labeling as well as either a physical layout redesign or a function allowing one to easily and quickly disable/enable the Cap Lock and Control keys, short of popping them off the keyboard.

    Best ergo yet

    This is the best most ergonomically correct Microsoft keyboard I've used to date. With the addition of macro and shortcut keys and controls, it sports some added convenience as well. These work good as set up- for things like zooming and web page navigation, or can be customized by the user to execute short macros. The latter is a huge benefit for those performing highly repetitive tasks- and these sorts of things are exactly what is to be avoided for the health of any user, so it also falls right in line with the purpose of an economic device. (E.g., repetitive stress injury.) I have chosen to leave the base attached, which properly positions the wrists at a forward and downward angle, but can be removed for those who may appreciate a less aggressive approach to ergonomics, and less apparent and impactful difference between normal keyboards and these types. I would say this, however: while I highly recommend these to people who know how to type the right way (not "hunt and peck") an ergonomic makes it more difficult to do work if you have to actually look at the keys to find your characters- because of its high stance. Removing the base or typing at the correct keyboard-to-user height may alleviate this issue significantly. While it does take some time to get used to, a professional or power user may actually see an increase in their WPM rate (characters per minute... I am an old guy who learned on a typewriter so.. lol) The only concern I have is for the longevity of the wrist pad. This type of material, in my experience, does wear and deteriorate over time. But I expect, even with this, to get no less than 5 years of daily work out of this keyboard. The pads may be replaceable, and they may be more durable than I expect, for sure. This is really just a stretch almost looking for a problem for the sake of that... but so that you know it will be less durable in this area.

    I think people need to use this before reviewing


    This is one of my favorite of many of the keyboards that I use. Given, this keyboard takes a long time to get used too, but if you are willing to devote the time to learn this then the experience will be very rewarding. One of the only complaints that i have is the spacebar. If you type a lot then this will be amazing for you as the right thumb gives a very hard plump making the spacebar sink. However, if you game a lot then this can be a trouble area as it can be a tad too heavy for the left thumb to hit a lot. For normal typing though, this keyboard is unsurpassed. This keyboard is very wide so if you have small desk space then you need to be aware of this. If you put on any of the height settings, then the keyboard can tend to set high. If you do not have any of the risers on then the keyboard sits surprisingly flat. The b takes a while to get used too as it is on the left side and you are probably used to hitting this button with your right hand. This is impossible to do because of the way that they keyboard sits. You will find yourself being able to last a lot longer typing though and this is one of the best modern keyboards on the market now. The model m still owns everything though, except in the comfort division :-P, this is where this keyboard really shines. So my thoughts are, if you are having pain buy this. If you are trying to learn to touch type, buy this NOW!!!!!!!! If you want a decent keyboard at a decent price with lots of add on buttons, then buy this. Definitely my top pick for price.

    One of the very best


    I'm going to write a review of the 4000 and the 7000, because they are basically the same keyboard only the latter is wireless. Pro's: This is one of the best keyboards you can buy. Typically once you go split-key you will never go back. I've been waiting for the laptop industry to figure that out for years... The cushioned wrist-pads are a MS original and help stave off carpal tunnel. To quote a character in the Matrix movies: "It's like wiping your a** with silk". Con's: The cord! You'll have to shell out $150 for the 7000 if you want to go cordless, which of course you do. Beyond the 7000's price, the chunky 7000 mouse may be absolutely the worst mouse ever made--- feels like holding a softball and is always tipping over from its own lack of balance. Why can't we buy the wireless 7000 sans mouse? Another con is the typical mushy feeling of the microsoft keyboard. Although to be fair, the 4000/7000 have the best key-feel MS has ever produced, even approaching the famed Logitech feel (Logitech has always kicked Microsoft's tail on the feel of the keys). You will typically have a LOT less typos with a Logitech and a MUCH faster WPM speed. Except this is the 4000/7000 keyboard we are talking about... a huge upgrade for Microsoft's key-feel. It's too bad that MS went wireless with the 7000 without incorporating Blue Tooth. A wireless keyboard/mouse combo is just that. A Blue Tooth keyboard (like certain Logitech models) transforms your computer in wonderful ways. You can send pics and syncronize data from a Blue Tooth phone/device, you can use cordless Blue Tooth headphones up to 60 feet away and other perks. Eventually Microsoft will figure out that having an on-board LCD screen is inevitable. Perhaps they'll even be the first to incorporate a color-screen using their patented keyboard scroll-wheel to zip between icons. That will be the day that we clean our screens of all icons once and for all. Someday after this we may even seen programmable LCD keypads. That will be the age when we finally have moved the hardware interface into the next millenium. Because of their indifference, for now Microsoft is about 8 years behind the technology curve of what is possible and necessary for keyboards. Other than that, for the price the 4000 is one of the best keyboards ever made. Definitely an upgrade over nearly any keyboard you can ever use. Try it and then BUY IT-- you will not be disappointed!

    Great for Fast Typists/Transcriptionists

    • My Best Buy® MemberMember

    I was never a fan of Microsoft keyboards, having used them for work 30-some years ago. For the past 15 or so years I've been rather attached to my Logitech Wave keyboard. I type so much that I was going through one every other year. Then it became one a year and now every few months I'm having to replace it as it becomes so hard to type on. I recently decided to give Microsoft a try after reading up on their ergonomic keyboards and currently have no less than 6 keyboards in my home office. Gave the Sculpt a try, but I just couldn't deal with the separate numeric keypad and the horrible mouse. I've also kept a wired Fellowes as a backup, but I just can't get used to that one. Last weekend I purchased two more Microsoft keyboards: the 5050 and this model, the 4000 (which is the cheapest of all the keyboards I own and lucky for me it was on sale!) After giving them a try, I was pleasantly surprised to find the cheapest keyboard my favorite. This model was the easiest for me to get used to and I've already programmed the 5 *favorite* buttons up top to take me to exactly where I want to go. I'd love a wireless version of this keyboard, but the wire is not a deal breaker for me. I didn't give this keyboard 5 stars as it remains to be seen how long this one will last me. I do like that it comes with an attachment that raises the part of the keyboard closest to one's body. I haven't used it regularly, but imagine I will at the first sign of wrist strain. I like the softer wrist rest--much nicer than the old hard plastic ones, but still wouldn't mind a little more cushion. I'd also prefer a larger delete button as in the work I do, I'm using it to delete pages and pages of text at a time and I miss my old Logitech Wave delete button. Still, Microsoft has come a long way in its development of keyboards over the years and I'm really hoping this one lasts me more than a year.

    Never take it away!

    I was doing a lot of data entry a few years ago, on a standard keyboard. By the end of the day, my hands were hurting, my wrists were swollen. I was having to wear wrist guard(s) or athletic tape to keep my wrist in a semi stable position. I just couldn't deal with it anymore and looked in to an ergonomic keyboard. I had a little previous experience with a wave keyboard, so I was a little familiar with the layout - but I had no familiarity with a split keyboard. I opted for the Natural 4000 because it seemed to liked overall. At first, the design is a little overwhelming and there is definitely a learning curve to a split keyboard. Be patient! I generally type 50 - 55 wpm on a standard keyboard and that dramatically dropped when I switched to the 4000. I had to look at my hands and the keys for a few weeks, but once your hands get use to the layout and placement, it's a breeze. In fact, my wpm has increased to 55 - 60. I still have to look down every so often because I may need to find a function key or character key. This keyboard saved my hands and wrists! I get zero pain and my wrists have yet to swell up again. I recommend it to anyone who does data entry and gets pain in their hands or wrist. I will never go back to a standard keyboard on a desktop again. I hate even using the keyboard on my laptop because it feels awkward and uncomfortable. The only downside to this keyboard is... it's wired. But that is definitely not a deal breaker for me. And through the years, the letters have started to wear away slightly, but since the layout comes natural to me now, it doesn't bother me any. I've had this keyboard for at least 2 or 3 years and it works just the same as it did on day 1!

    Great keyboard


    This is my second Microsoft ergonomic keyboard. I've had the first one for years until it gave out this week. I would not consider my self to be a keyboard guru, but spend enough time to be discriminating, and my old one got replaced with one the same model. Other than the finish on the keys, the two boards look and feel identical. I rate the board as follows: COMFORT - the best!!, DURABILITY - I've had the first one for so long, I don't remember how many years old it is. Just about every part of my computer has been replaced while this board has stayed, So unless this new board wears out or the paint wears off in the near future durability remains excellent, I'm going to politely have to disagree with those who claim the quality has gone down. ERGONOMICS - I don't find the keys any louder than any other keyboard I've used, and quieter than many. I've not ever had a sticking problem - not even on that oversized space bar. VALUE - I could have spent four plus times more money for a keyboard, and not been any happier. The only complaint that I could possibly have is that other (non-ergonomic) boards are slow for me, and my error rate goes up drastically when I have to use them. This keyboard felt natural from the first time I used it! Love it!
