I almost exclusively play handhelds now. I very rarely find myself at home with nothing else to do besides play video games on my consoles. I can play my handhelds in the bathroom, in the bed, in the car, on my breaks at work and between classes (and if I'm feeling frisky I can even play them in class [ohohoho i'm a bad boy!]).

I have the Game Boy Pocket, Gameboy Color, Gameboy Advance SP, DS Lite, 3DS XL, PSP (x2) and the Vita.
