I think the PS3 is cool with its affordable blue ray and hard drive now that the price is coming down.
The problem with the PS3 is that it is so expensive to develop games for. It's going to take 2 or 3 years before third party developers can _consistently_ produce high quality games for it.
Another thing that I can't stress enough is that the Wiimote configuration makes FPS games fun on the console whereas before they were only fun on the PC. The mouse and keyboard is far better than PS3 and 360 controllers but only a little better than the wiimote.
I think pretty much everyone's ideal system is a system created with 360 online, PS3 technology after about 3 years maturity and the Wii's control system.
