PC, NES, SNES, N64, Gamecube, PS2, PS3, Dreamcast, Game Boy, Game Boy Color. I had a PSX though I gave it to a friend since I have no use for it anymore, and I also gave my sister my Genesis years ago. My sister also has a Wii and a DS, so I can essentially play those whenever I want. Of them all, I'd say my favourite lately has been my PS3 since Uncharted is absolutely amazing. Had Portal not been released this year, I'd say Uncharted was my favourite game this year. Overall though, My PS2 is my obvious choice for favourite (though if I included every game my PS3 could play, I suppose it would still be my favourite). With over 60 games for it, with some of the best games I've ever played included among them, it's hard not to love that system to death.
