user interface? the XMB is far superior...
custom sound tracks.. some PS3 games have it and in-game XMB will be released sooner or later.
Digital downloads.. now thats a piss poor reason... of course a 500MB game will take longer then 150MB game to download. As for the auto-install, its there if you download your files individually.
Web. the PS3's and Wii's web browsers say hi. And HOME says im coming.
Truly a garbage list put together by the biased that is gamepro.
