I'd steer well clear of the lot of them. Currys, dixons, comet, pc world, all run by morons who are out to rip off folks. Shop online, I got mine from Laptops Direct, delivered in 48 hours
Ordered one today from them Should have it tomorrow. Basic thing really. 2.1ghz dual core Pentium, 3 gig of RAM (I will upgrade that to 4 myself) 250gig HD, Windows 7, decent graphics for what I need... Photoshopping and stuff! Not a bad price either.
