I've never really gotten into the laptops as I prefer having a "war room" with my PC, ergonomic chair, and all my accessories within easy reach. I have played around with a few, however, and it sounds like you got a good one.
What I would like to do is build my own PC as one of the commenters talked about doing. If anyone wanted to write a nice thorough post on how to do that, I'd love to read it....
Have fun with your new toy!
My main machine at work is a custom build. I have a couple of hand made boxes in my office. Laptops are nice because I can still sit on the couch next to my wife and work. As much as I love my desktop, I have to isolate myself to use it.
