My PStwo? No. I have no plans to buy a PS3 any time soon, and it's not guaranteed to be as compatible (problems A and B? No use of the memory cards and controllers from the past).
My XBox? Um... don't have one. Actually tracking one down, if it's a deal, to play the XBox games I actually have (don't laugh, but I have a shelf of games for a console I don't have), until they're playable on the 360. Either way, an original XBox, via some reworking, would be the console I take to campus.
My Gamecube? Now here's a quandry. I have two black GCNs (one won in that Planet Gamecube contest a few months back). One is definitely for sale, and that's my non-progressive-scan-outputting, mint in box one. The other is problematic. It's the original model, but I don't USE that output. BUT... the Wii has not shown support for the Gameboy Player... which I never use... AND... I like to hold on to systems, or at least recollect them later.
My PSP? It's been sitting in trunk for the better of two months, awaiting selling for a Neo Geo. Massive upgrade I won't regret at all.
Gameboy Advance SP? Hell no. It's the NES edition.
Gameboy Micro? Been trying to sell it to grab the Famicom edition.
Nintendo DS? I'm on my second (I sold the first to get this Blue one), and I'll sell it to get the Lite. I have buyers lined up who want the system for a steal.
