Re: laptop for my mum ;p
pounds is England.. newegg doesn't ship across the pond.
as far as laptops go, dells vostro line is good, Acer's are nice, Compaq is for budget, hp is really good all around, Toshiba is a cheap space heater. Acer & Compaq are more for being on a budget, so I would really look into an HP or Vostro if you can still get them...
any proc will be fine, i'd stay with intel unless you're going to be watching blu-ray, then go with amd. Go with at least intel's x4500 gfx, or a dedicated card if you can. dedicated is always better, but the x4500 is most likely better than the 6150/7150 onboard cards. 3-4gb ram and a smexy screen and you're good to go.
