I've found this an excellent computer. I move around a lot so I wanted something light and slim.
However it's also great on power - it has windows 2000 and 128 SDRAM.
I'll never get through the 20GB hard disk but it's nice to have and does not add much to the cost.
The other great thing about it for a mobile user is that you can plug directly into LANs and be up and running on other people's networks without having to go through all sorts of modem, DNS pain.
Convenient - highly mobile - and a very reasonable specification.
Is it worth the £2200 I paid on Tottenham Court Road? Cheaper would have been nicer but I've no complaints.

Actually I do have a gripe - battery life is a paltry 1 hour usually. You can buy an excellent five hour battery (c£260) though which will ensure you never need plug in during meetings.
