I'm looking to get a Dell laptop that I can dual boot windows 7 and Red Hat Enterprise on. Is it safe to assume that most laptops will be compatible? Basically, I need to be able to install RHEL 5 so I can get a nightly backup of our current server on it. It needs to be portable so that in the case of a flood (I work at a boatyard/marine distributor now ) it can be removed and the business can still function. It needs to be able to support RHEL 5 to maintain compatability with the current server. Beyond that, I don't have many specs. It's running some old green screen legacy system, so...

It's been so long since I've been able to work with Linux, I'm a bit out of touch with where things stand. It's good to be back though.
