I'd say different, they are overpriced, you're paying for the branding. And from a few people that I do know that has had and used them they weren't that happy about them.

Overpriced
Overheating issues - An M17xR2 I used had severe issues and the laptop only lasted under 2 years. The small fans can't cool them down enough and they sound louder than a cheap hairdryer when pushed.
Serious health risks (from the overheating/electrical fire)
Crap customer support and lack of drivers.

Get a desktop for that money if portability / space isn't a problem.
