1. No
2. M1330 integrated is more than enough to run Vista aero, but not much else. It underperforms on even basic 3D games like CivilizationIV.

I've had mine for some time, there are some other 'gotchas' to be aware of. All ports are on the sides, so don't expect to be able to leave in any dongles or usb receivers and still slide it into a case or sleeve.
There are some crackling issues with the audio. I use a toneport to play guitar, and Torq Xponent to DJ - my old P4 3.4Ghz XPS is still used for those functions, since the m1330 audio just isn't very clean.
Otherwise, its a great laptop and a complete steal at this price. Slap in a faster drive and more ram and you'll be good to go.
