Go with a Dell. I have had three of these things in the span of 4 years. One always goes with me on travel and it can take a beating a keep on working.
It's hit the floor board of my car after slamming on the brakes, hit the ground a couple of times and when its in the carry bag that I have its always getting tossed around...
But that S.O.B. still powers up everytime...
