I go through phases. Currently I'm still in the middle of Echoshift on the PSP, but I've been watching TV the past week.
Other than that, I still play all the versions of gameboy, most recently tetris DX on a pocket, I was playing Shadow Dancer and Ranger X on my Nomad about 2 weeks back, and before that I was playing Uncharted on the Vita.
I don't often take the GT out just because it's so valuable, particularly to me, but I hope to get some kind of portable solution soon.
And as far as my phone goes... some Angry Birds, but the games are so damned expensive.
