Laptop advice

[vargojones]

Hi all,

my other half is wanting to purchase a laptop, with the following requirements:

plenty of mem for photos and music (2gigs?)
wireless adapter
not too weighty and a decent sized screen 15"+
won't be obsolete in 5 days time
has the a vague chance of playing the odd game
no more than £600 ideally

i think that's about it.

Thanks in advance
