Right now the PS3 Linux scene isn't doing much. You can't access the RSX graphics chip so don't expect any new drivers or future game support until they manage to get to the RSX.
They can create an XBMC type setup though, which would be cool.
Well chances are the iPhone cost them millions in expenses so by charging this much off the bat, they'll recoup their losses quicker and later on a price drop will revitalize interest in the phone.
Still hate Apple though.
Well I don't own a PS3 so I don't think that'll happen, but the browser has video playback and supports flash so I'm sure if someone else tested it, they would get it to work.
Sort of a trivial thing, though.
