Think about what you are really going to use it for.
If all you are going to do is sent e-mails, surf and watch the odd dodgy DVD then I suggest something at the lower end of the market. They are nearly all wifi these days too.
Don't waste your money on high spec if you are not going to use it.
BTW, I have found a good source of cheap laptops (and desktops & PDAs) on E-Bay. HP off load last weeks models but you still get the warranty etc. Check out HP Renew Shop if you're interested.
