thanks jamie
i may actually be changing tack slightly after going into a local supplier.
I have actually decided (almost) that a 14.1" widescreen is going to be better for my needs. Jut that bit more portable.
main editing on my desktop and really just storage and 'checking' (settings, sharpness etc) whilst in the field. The 14.1" being easier to manage in car etc. And tbh if away for extended period then i will 'learn' the laptop wrt reading he screen correctly.
To this end i'm looking at a dell again. The portable 640m. I have tested the screen and the performance(dual core cpu, 7200 rpm drive, 1gig min ram etc) and i'm quite pleased with the overall package and it's also 250 gbp cheaper than the sony.
Not ordered it yet but unless something seriously changes my mind then i think i will be.
thanks for your input,
cheers,
