Sorry, I should have given more information in the first post.
The laptop is for my mum who isn't exactly what you'd call a power user. She will literally just be using the laptop to get on the internet for day to day use. It will more than likely always be plugged in, but would prefer a laptop so she can use it in the lounge in front of the TV.
I have been looking at the Vostro 1000 but not sure how good the lowest spec machine is. Looking at the mid-spec one I am not sure whether it is best to get her XP - which she is used to - or future-proof it a little more and get Vista but as the only version of Vista that comes with it is Business I am not sure this would be suitable.
How good is the lowest spec Vostro? I am trying to save my mum as much money as possible.
Thanks for your help guys.
