I own XBOX 360 and Wii, I'll buy PS3 for Christmas.
Each of this consoles is great in its own way.
You know, people enjoy being opposed to each other, that gives identity, but if you like videogames then the so called "console-war" just makes no sense at all. Unless you have financial issues you should just buy them all, so you can play all the best videogames out there.
(PC sucks)
Edit: I also own DS and PSP. Yes, videogames (consoles) are my main obsession

In a year all your consoles will be outdated while my PC just takes a simple upgrade.
