Reasons you don't own the other console(s)

[KungKras]

Don't own a DS becasue I can't afford one right now. But I will get one eventually.

Don't own a PSP because it has almost no games that appeal to me.

Don't own a PS3 because it is very similar to the 360 and the price doesn't justify buying it only for the games I want that aren't on the 360. But it still has some nice games that I could imgaine myself buying it for had I not already owned an HD console and having to chose between the two.
