Would be awesome to see this as a Chromebook, instead of an Android Tablet!
In terms of power, a Chromebook is equivalent to a mid-tier tablet or a low tier computer. They use low end CPU's with high energy efficiency.
If you want long battery life, but do not use processing intense applications, either is fine.
