If you have not held the new MacBook in hand, it is almost impossible to think how a computer can be so light and so thin. In some ways, it almost seems like an iPad with a clamshell keyboard attached to it. To make space for the small form factor, many 'normal' features had to be removed: no CD drive, no USB ports (save for the USB-C charging port) and no HDMI port. This computer was truly designed to be ultra portable and is not peripheral feature heavy. While I was looking for a computer that is easy to tote around, this could be a reason to consider a different model for some users.
Since I was switching from a MacBook Pro, I found that the keys (like the new Magic keyboard) are more shallow and take some getting used to. This makes for a small learning curve, but overall it is a non-issue.
The loss of some factors of convenience (no USB drive, etc) are more than balanced with the impossibly thin design of the new MacBook. It almost seems ridiculous when you look at other larger laptops after using this computer. Keep in mind, if you don't already have one you will need a bluetooth mouse, etc to get the job done. More than just a cosmetic choice for the MacBook is the aluminum shell. I opted for the gold finish, which looks stunning. Since the laptop is so light and thin, the aluminum makes it feel like the construction is sturdy and not flimsy. Overall I am very happy with the computer. I would urge that anyone considering the device thinks long and hard about the need to use peripherals and if they can live without USB/ HDMI ports and a DVD drive natively built in to their laptop.
