Where do we reckon the best place is for a new laptop??

I need a new house laptop, and having had my fingers burnt with the present, failing, crappy Dell, I want some better value.

Requirements:
16" screen or bigger
Decent Keyboard
Up to date Chip
Windows architecture
it's for browsing, watching films and light word processing

Doesn't need:
Hard drive space, I have an 8Tb Synology NAS, current laptop has filled only 150Gb of 900Gb onboard
Fancy graphics card - nobody does any PC gaming or graphics manip in my house
Named brand
onboard CD/DVD - got external

Budget.... Ideally £500, and if you bear in mind I don't want a gaming rig, or a 2Tb HDD or (shudder) Apple......

an online retailer ?

an eBay store ?
