I would like a link to the PS3 differences (between the 20 and 60 gig versions). Personally if the cheaper lacks PSP support, HDMI and memory stick slots then I dont care because I have no PSP, cant afford a HD-TV and dont have a memory stick.
Now the question is, whats the HDD space for. I assume not for running games off of images (atleast yet...) I would like to think its for downloads like maps, characters, saves, skins and perhaps even game patches... maybe movies and music also. Is it worth spending the 100$ for a lousy 40GB???
