Well to preface, there is a little bit of a learning curve with this. Since it's not your average OS as it's built primarily around Google Chrome you're going to likely run in to a few issues, especially if you're intent on using it with standard Desktop software available on Windows or macOS.
With that said, once you are able to get past that fact, ChromeOS is actually a really nice and slim operating system. There's really not a lot of overhead, and it may seem like an i5 or i7 and 8 or more Gigabytes of RAM is overkill, depending on your use, it may be just perfect. There are methods out there to install Windows on to once of these, however, that's entirely at your own risk.
I have to say, I do have a Windows 10 tablet and I find myself going back to this more. I think that is in part because this has twice the available RAM, but all the other specs are nearly identical.
It's fast, very fast, and that is in part due to the relatively small footprint of ChromeOS. It only takes a couple seconds to start up. Setup was a breeze and very fast. It really just works, and I love that.
One of the biggest things a lot were clamoring for with ChromeOS was the ability to use app's from the Google Play Store. With some of the latest Chromebooks this has become a possibility. Now it is not perfect, and some apps just don't look right, and some apps just work flawlessly. There are some Mobile games I play on here and it handles them just as well, if not even better than some of the most powerful Android or iOS devices. The Pixelbook is currently the premier Chromebook that does offer this support for App store compatibility. Other more recent Chromebooks are slowly becoming available, however the Pixelbook has it right out of the gate.
One caveat with this however, as this does use an Intel i5/i7 depending on which you settle on, this is only utilizing their integrated graphics. While potent for a lot of standard run of the mill games, it's not going to be able to utilize some features found in High-End Android, iOS or Windows based devices A gaming machine this is not, but it will not let you down with typical apps in the Google Play Store.
I will note, when using it for games for a long time, it does get quite warm to the touch around the top of center of the keyboard. So if you are using it for this, I would highly suggest to use it in Tent Mode, or Tablet Mode so you're not keeping your there or on your lap. It's not enough to cause an issue, but it can be a bit uncomfortable with heavy tasks, but this is true in most devices, so your mileage may vary with how you use.
You can pretty much throw just about anything at this. Even the battery life on it is great. For a heave session of web browsing and gaming, I'm sure I got around 6-8 or maybe even more hours. It uses USB-C to charge, I believe Ver. 3.1. It only takes a couple hours for a full charge with the adapter it came with, which is also fast charging. The cable itself is USB-C on both ends, so this will not connect to your run of the mill USB charger, you would need an adapter for that, or USB 2.0/3.0 Cable. I wouldn't recommend anything less than 3 for optimal charging.
The screen on it pretty darn nice. It us only an LCD, which is pretty common for Notebook Computers. It's a little thick, and the bezels are a bit of turn off as there is quite a bit of space from the edge to the screen, probably an inch on the top and bottom and half an inch on the sides. It also get's plenty bright. If you use it outside, I don't see you running into to many issues, but direct sunlight may be an issue as it does have a reflective glass screen. Also, the ability to use it in either Notebook orientation, Tent orientation or Tablet Orientation is really great and the hinge design seems top notch. It doesn't feel loose, and I've had it for about 2 or 3 weeks now and it's like I just took it out of the box.
Also, this is more about the construction of it, on the sides of the touchpad, there are softish like pads to rest your wrists or palms on. It also acts as a cushion that the screen will rest on. It also has this material on the opposite side of the device to cushion the screen when you have it in table mode. I does get a bit unwieldy as when you hold it, you're likely going to want to hold it in the middle, the problem there is that you are going to be pressing down on the touchpad. While it doesn't affect anything, it could over long use wear it out. Thankfully there's those cushioned pads on the side of the touch pad you can use so it is a little more comfortable. The all aluminium build of it definitely makes this a standout as it feels incredibly well built. It is a bit heavy, but when it comes to solidity and durability, I hold a lot more faith in this than I would in a Notebook with a bunch of plastic.
They keyboard is very nice, and has a great tactile feel to is. I also appreciate that it is backlit so if you're in a dark place, you can still see when you type. They also did not stop with lighting the edges of the keys, the letters themselves are also illuminated.The touchpad is also very responsive. I did experience some false touches with it with the tap-to-click feature so i did turn it off. There's not a way to decrease the sensitivity of the feature as it's an all or nothing setting. Aside from that quirk it really is an all around great device.
Also one of the other cool things it does feature is Google Assistant. This is something that has been slowly rolling out to other devices. It first started if I recall with the first Google Pixel and has slowly trickled into other devices. It's a really cool feature especially if you have a connected home with things like lighting, WiFi Thermostats, Speakers, Stereos, Security Systems and such. The google Home app also does work natively on the Pixelbook.
When it boils down to it, in looking for a device that is a Notebook, you want to determine how to you want to use. If you're looking for something such as casual games, either a iOS, Android or Chromebook device will fill that role, so longs as you're not looking to play things from something like Steam, or another Desktop PC oriented app. If you're looking for productivity, this can also do that as you can get MS Office on the App Store. Also, you can even do drawing on it and it comes with LightRoom as well. If you go this route, you'll want the pen, and that's another $99 sadly.
If none of the above is what you need or fulfills your needs, you will want to look for something with a dedicated Operating System like Windows or macOS.
Overall, if you're looking for something that's not more than you need for everyday use, this is a great device, and I'm sure I will enjoy it for years to come, or till the next big thing at least!
Oh yeah! Since this does have a glass screen, keep a Microfiber cloth handy, cause it picks up fingerprints like it's going out of style.
