I just placed an order for a Dell Inspiron 6000D, using one of Dell's recent $750 off deals. With any luck, it'll ship in a couple weeks. In the course of doing research on the machine, I found this site describing James Carter's experiences with the machine. It is without a doubt the best, most comprehensive laptop review I have ever seen. If you write a product review for a laptop computer, you should emulate this.
Something else worth mentioning is that laptop vendors typically use standard parts in their hardware. While they don't publicize part numbers (partially so they can switch suppliers), it is possible to find datasheets describing things like LCD panels. While it takes some inference to figure out what part is being used, this can reveal statistics about LCD panels that might otherwise be hard to find. While Google is your friend, this site has a bunch of links to useful datasheets.
PS: I've ordered the WUXGA (>2 Megapixels, ~140dpi) display with the 128MB Radeon X300 video adapter. If on screen content isn't too small, I expect the detail to be fabulous. I'll post comments (and screenshots) when I get some experience with the machine.
