Personally, I'd have just gone with the Dell XPS 1530. That thing is a SEXY beast. Of course, though, if you had more money than money than money you have money of (yes, really), you'd go with the Dell XPS 1730. I've got a Dell XPS 1710 (company hand-me-downs rock!) and it's beautiful (if not old, poor little 6800 ultra).
But then, the full sized keyboard is what would make me go that way. That, and I like BIG laptops. The 17" 1920x1200 screen is disgustingly awesome. I don't think I could use a system that wasn't at 1920x1200 now. I'm spoiled.
Good luck with the new system man.
EDiT: WAIT WAIT WAIT, only 2gb of memory? You got XP with it, right? Vista is better with 3.25gb of memory (or go with x86-64 and get 4gb), but it's not as if it'll die or anything. Memory is the easiest thing to upgrade aftermarket anyways, so I usually just buy the cheapest through Dell and throw in what I want later.
