Hey Peter
been a while. The second laptop I decided probably better to keep for now (Hence the change in in the ad) but the XPS M1330 is still for sale - and a better price
Being a 13" the resolution is 1280x800. I'm not sure if its glossy or anti-reflective, but I've never had a problem with it. Yup it does have a dedicated GPU, GeForce 8400M GS with 256Mb RAM.
Just in the process now of editing the ad with the proper specs.
