Very fast, Oblivion runs as well as it does on my C2D/Nvidia 8800GTS desktop.
Great screen! Big and beautiful, just like me.
Speakers sound surprisingly good, nice and loud compared to my Macbook.
Quiet and relatively cool.
The keyboard has a nice feel to it.
Fingerprint reader gives me geek street cred.
HDMI and ESATA ports.
Piano black finish is a fingerprint magnet.
Heavy as shit, north of 10 pounds.
Definitely a desktop replacement, see the photo comparing it's size to my Macbook! I'm pleased so far, but my opinion of Windows Vista hasn't changed. It's stable and seems fast, but I wish to Jah I could load XP.
