Thanks again guys, I'm going to go with Office Updates suggestion and bring in the laptop with me and get them to show me it working before I part with the dosh.
Thanks also for the network suggestions but I'm not in the UK and I have only two networks to choose from. I've spoke to both and theyre "pretty sure" it will work but not exactly confidence inspiring, they basically wanted me to but it and take it home and try it, but I dont trust the after sales service so...
