Sony failed to mention in its press conference a few differences between the $499 and $599 PS3 models -- besides the 20GB and 60GB HDDs, that is. According to a PDF on SCE's Japanese website, the less-expensive version is lacking the following: 802.11b/g wireless capability; MemoryStick/SD flash slots; and an HDMI video-output. Looks like potential PS3 owners who want to take advantage of these features will need to shell out an additional hundred bucks, but hey, at least every model comes with a HDD, right?

Also worth noting, The PS3 controller does not have any sort of vibration feedback. Apparently, it interfered with its motion sensors -- or maybe Sony is still feeling the heat from that Immersion lawsuit.
