Google I/O is mostly for developers, but the show can offer a lot of interesting sights for your average smartphone geek. Between robots, a Switch Pitch ball, and giant Android figures that doubled as device charging stations, the conference can be a visual feast. That's provided, of course, that you like the color green.

My biggest attraction, though, is the glass case that shows Andorid phones from around the world. It's a great resource for checking out handsets that aren't sold by a U.S carrier.
