You probably noticed the huge gap between NES and GCN. It was filled with Gameboys. No sense listing the Gameboys, I've had all of them (including GBA Micro). I also now own DS and DS lite, as well as a PSP.

In the last 8 or so years, I've had a few PCs/Laptops, though I never really played much games on them.

My first Xbox was modded, and I bought another one because I couldn't play on LIVE with the modded one (I could, but I could get banned). I later gave it to a younger cousin. I still have both 360's. One red-ringed.
