Can't comment on that particular model but I have Travelmate I use at home and it has been reliable and stable for the 2-3 years I've had it.
I also have a new Travelmate from work (a large secondary school) and again reliable and robust. All our staff (some not very IT literate or keen) have one of varying ages and they survive being dragged around and abused quite well. Our technician has stuck with them because of his experience of their reliablity in use.
Hope this helps.
