Yeah i'm really liking the system so far.
I need to find a decent wallpaper at the moment though, although i sorta like this one that came bundled with OSX tho:

World of Warcraft Running on the OSX Version:

Its also quite amazing how compact it is. The system is a 2.66ghz Intel core 2 duo with 2 gigs of ddr 2 800mhz ram, 320gb hdd. The video card is pretty ordinary, only a ATi HD2600pro with 256mb's of ram. But i dont really use it for much gaming except retro.
Has built in webcam, microphone, wifi/bluetooth. Firewire 800 and 400, 3 usb ports, DVI out if you want to hook up one of apples crazy cinema vision monitors or one of your own. Dual Layer Dvd burner (slot loading)
It fits on my desk very nicely.
