It's essentially an internet browser, if you're okay with it being able to do nothing but use Chrome than it's usable for you!
The Chrome App Store does have some games, and some good extensions as well as other various apps, so it isn't completely garbage, but it can't run any 3rd party applications which sucks (for me, at least).
Specs aren't great, but you won't need great specs to use this computer. Very good little device, just ensure you know it cannot do nearly as much as a Windows PC that's in that price-range.
