I guess this is a website about video games (a website. about video games.) so I'll tell you about my video games.  I own the three current generation consoles as well as a decent gaming PC.  The PS3 is probably my favorite system in terms of hardware and interface, and those things are pretty important to me.  But it doesn't really have that many games I like yet, and the multi-platform games are often significantly worse on the PS3.  However it does have a few really cool games on the PSN.  I also enjoy PC gaming, especially with Steam really coming into its own these last couple years.
The 360 has had a lot of good games up to this point, but the system is so loud and unreliable that I often avoid using it at all these days.  I mostly bought the Wii to confirm my suspicion that the Wii was not worth owning.  I guess that makes me an idiot.  Oh well.  I own a DS as well, but I don't even know where that thing is.  I'm rarely in a situation where I want to play games on a 2" screen.  Even if there are two of them.  I'm sounding pretty anti-Nintendo here, let me just say I owned and liked the Gamecube.
