This gen has broken down my system bias. I started off somewhat anticipating the gamecube, and not giving a shit about any of the others. I found myself impressed by Halo and PGR and Morrowind, ended up taking over my brothers Xbox and enjoying the system quite thoroughly. Got my fill of the Cube launch with my best friends Gamecube, very disappointed with SMS and SFA. Waited until the platinum cube/gba player bundle and snapped one up for 150. Bought a bunch of games and love the system, but mostly for its excellent multiplayer games. GBASP quickly becomes my favorite system, play it nonstop. Moved out, bought my own Xbox. Love it. Got a DS a few weeks after launch, love that too. GT4 loomed on the horizon, and I love racers. Always hated Sony hardware, and only interested in the RPGs on the software side. I caved in and picked up a used one a few weeks ago for 70 bucks from a friend, GT4, a few used/cheap games, and have been playing it nonstop. Just got my DFP wheel tonight. It is definately a solid system with a huge selection of great games. I love all my systems, and I can see myself fleshing out my libraries for each for years to come. Definately looking forward to PSP, Xenon, Revolution, PS3, and upgrading my PC.
The one console future arguement is stale as hell, they all offer something unique that can't be done on one system. If you can't afford them all, then exercise some self control and wait.
