Same reason I bought one last year.
360 and PS3 have pretty much the identical libraries, therefore games are not much of a differentiating factor.
However, PS3 is not that much more expensive and it includes free online, browser, built-in batteries, and a bluray player. Which, for the small difference in price, makes it a better value to the average consumer who doesn't care about Halo or Gears.
Additionally, when everyone one you know has had to replace their 360 at least once, it doesn't really help.
