I'm not sure why this is better than the cheapest macbook air?Similar battery life, similar processor. 4gb more memory, smaller hard drive. And the cheapest pixel is $100 more. What do I get for that $100? For me the downsides are: can only use apps from the chrome web store, no unix command line (maybe it exists and I don't know?).
I'm really happy someone is trying to compete, but not sure why I would buy this.
If you want a full featured local linux command line, you can switch to developer mode and install one in a chroot via something like https://github.com/dnschneid/crouton
This does sidestep some of the security features of the device, but it's fine if you really want it. Or you can just ssh somewhere.
