And re Thinkpads, DaveRo. My father has one of those. That one does have access points at the back.

I'm not happy with its Linux compatibility for wifi and bluetooth (and use a dongle for that...) but if build quality was my measure, I think its a nice machine.

I don't know the range but if this one is anything to go by, they are well put together. The one he has, even in the feel of the keyboard is superior to my rather more expensive ASUS.
