:Just read something else:
Marc Whitten reveals that you'll be able to copy full games and play them directly off the hard drive to shrink load times (and silence disc spinning), though you'll still need the game inserted so they know you own it.
NOW that is news! Bye bye continuous loud DVD drive...(except for authentication)
Yep 20 GB will not be enough let alone 60 GB or even 120 GB. Too bad you can't just slap in any old 2.5" Sata HDD like you can with the PS3. $125 for a 250 GB vs $180 for MS 120 GB gimped HDD.
