Desired minimum spec:

Intel 4th gen Core i7 (i5 considered)
8GB RAM (easily upgradeable, so 4GB isn't a problem)
500GB + 8GB SSD
13.3" full HD Touch Screen
Weight comfortably less than 2kg
Windows 8.1

Price less than £700.

This jobber seems closest to the mark so far:

but the killer is the screen resolution, which, although not shite, ain't particularly great either.

Any suggestions? Thanks.

(For a brief moment I was tempted by Macs. Then I came to my senses.)
