I recently purchased a Compaq R4000 notebook computer from HPShopping.com and wrote a review of it for NotebookReview.com. So far, I have been very happy with it. It runs cool, and can actually serve as a "laptop" without burning your legs. It is a bit heavy, but then again it is supposed to be a desktop replacement.
Anyway, read the review here: Compaq R4000 Review.
Note: By the way, KingMax RAM is really cruddy.
