Thanks Mark W

I am currently looking at two options

Fujitsu Siemens ESPRIMO Mobile V5545

Processor: Intel Core 2 Duo T5550 1.83GHz
RAM: 2GB DDR2-667MHz
Hard Drive: 120GB
Display: 15.4" Widescreen TFT
Operating System: Windows Vista Home Premium
Graphics: ATI Mobility Radeon HD2400 128Mb

or

Acer TravelMate 5720-301G16Mi

Processor: Intel Core 2 Duo T7300 2.0GHz
RAM: 1GB DDR2-553MHz - would expand to 2Gb
Hard Drive: 150GB
Display: 15.4" Widescreen TFT
Operating System: Windows Vista Home Premium
Graphics: Intel GMA X3100

With the Fujitsu at £509 and the Acer at £408 + memory upgrade

Going on your advise I think I will go for the ACER
