Because of my rather nomadic lifestyle at the moment, I figure it'd be for the best if I went for a desktop replacement rather than a new box - especially given the fact that laptops can do some pretty amazing things nowadays.

Essentially what I'm looking for is a laptop on a par with desktops. Portability doesn't concern me too much, although I'd rather not have a total brick. Battery life isn't too huge an issue - though obviously I would like near 2 hours non-intense activity.

Oh and they'd have to ship to the UK.

What I'm currently looking at is some customisation of the Rock xtreme ctx pro range. Link

I'm currently thinking along the lines of the T72 with the GTX 256MB and 2Gb RAM.

Alienware's beasty also looks quite tempting but its running AMD and to get a similar spec would put it over £2000.

Dell also have an interesting offering - but 5400rpm harddrive is pretty offputting and also - ITS DELL!

Any thoughts?
