Hypersonic can't plug in digital LCD, not sure if it can do dual monitor, only 10/100 ethernet (People may not need gigabit ethernet speed but not need a cross-over cable with gigabit is nice), only 11mbps wireless, Bluetooth optional, no cool backlit keyboard / light sensor, no FireWire 800 and FireWire it does have in only mini port so can't supply power to things like portable drives and iPod.
I do like the fact it has a full numeric pad. The space is there, so why not.
S/PDIF 5.1 Ch Digital output is nice. Not sure the built in "4 speakers" will sound that great though. (Not that built in speakers on any laptop sound nice)
No mention of battery life. And price.
Not a bad laptop. Could be great for running FinalCut. er.... Well it has DVD-R so iDVD or DVD Studio Pro will go nice. er....
