Wii = Potato chips... Looks great, tastes great but when you eat it you realize there's not much there (Controls are cool, lacks storage, movie playback, and graphics are last generation)...
360 = Double Big Mac... Tastes good, lots of people like it, but quality (hardware) nutrients is suspect.
PS3 = Chinese food buffet... Looks great, tastes great... Left feeling hungry an hour after you eat though (Doesn't really live up to expectations)...
