Just double checked the email. It actuallt states "XP is fine but not Vista"
Maybe windows 7 will be ok.
Will email them to find out.
That makes more sense to me, and would definitely think that 7 will be the way forward for you.
Assuming it is, what's your budget, and what do you want from the machine?
It doesn't need to do much so just something basic really. Memory and speed aren't primary concerns.
Will be used for setting up CCTV cameras and wireless links. Very low demand applications.
I think a £200 job would do but I don't mind going up to £500 for something that looks a bit nice with a decent screen, perhaps with a bit of software included such as MS Office just in case.
Battery life is important because setting these items up will use the laptop's power.
Something light would be an advantage because it won't always be possible to place it on a desk.
