I have a fairly good gaming PC, a PS3, a DS Lite, and a GBA SP.
The computer cost around $600ish when I built it two or three years ago, and can still play Crysis 1 perfectly fine (not that I actually play Crysis anyways). PS3 hooks into the same 21" monitor as the PC, so that cost a little bit of money...and both the PC and the PS3 route audio though my Creative Xmod for consistency. No speakers here, I consider them rude in situations where I have to live in a single room with a roommate.
I have about a dozen DS games, and half a dozen GBA games and some GBC games, that I play on the DS Lite and GBA SP. This is what I'm trying to make my primary game time. Handhelds are where it's at as far as I'm concerned. Adore games like the Summon Night series, and I'm utterly apathetic about every single release on the PC in the last 3 years and for the future years to come. Need to play the PS3 more often too, since I really do enjoy Bayonetta, and I'm waiting for the Ico/SoC bundle to come out in October (or whenever it's supposed to be released).
I'm thinking of going in a different direction for my next computer. I want to make a small form factor machine that's tailored for straight up internet, video, and multimedia, with very very VERY light gaming if any at all. I might even put Linux on the thing, which just goes to show how far I've gone away from PC gaming.

Edit: Oh and I used to have a Wii that I played Muramasa and Fragile Dreams on, but after I got the balance board thing for my mom last Christmas it's de facto her's now. Really should get a new one for myself though...I liked Muramasa and Fragile Dreams...
