1. PSP
2. Wii
3. PS3
4. DS
5. Xbox360
(6. DSi, 7. PSP 3000)
PS3 and Wii get the most usage, probably comparable, can't really say which I use more. The Wii owns a lot of that time to Wii Fit/Plus. DS gets decent usage, although a lot of it is educational (kanji etc).
Only used the Xbox360 for some JRPGs around the time I bought it, PSP more often but a lot of the time as a media device. I still use my PS2 quite a bit (PS3 only partially compatible and only for US disks).
