In short, the Nexus 7 is everything I wanted then. Of course expectations have risen over the last two years, but the Nexus 7 generally rose the occasion there as well. I think this sets the bar for all other Android tablets. Many tablets will fail to meet it.
Broadly speaking, I’m not sure there is any other 7″ tablet as good.
So, if a tablet wanted to beat the Nexus 7, what could it do? They could include a rear facing camera and a microSD slot. For some people, a 10″ tablet would be an improvement. I find that larger tablets lack portability. 7″ fits great in cargo shorts, and for me it also fits in the front and back pockets of most of my pairs of jeans (but I can’t sit with it in either pocket).
By the way, the Blurex Ultra-Slim Case for Google Nexus 7 inch Tablet is a nice case for the Nexus 7.
