PC World has writen a review on Dell's Latitude D510 notebook. Here's a short snip from their test report:

The least assuming of Dell's business notebooks, the Latitude D510 lacks the flashier features of its siblings--the D610's smart card reader and the D810's wide screen, for instance. What it does have is a handsome charcoal-colored case, a good keyboard, a handy multipurpose bay, and a long-lasting battery, all for a good price. The $1509 D510 packs a 1.6-GHz Pentium M 730 processor, a 15-inch XGA screen, a DVD-ROM/CD-RW drive (a $59 upgrade from the standard CD-ROM drive), and a 40GB hard drive. You can bump up the configuration to include a DVD burner for an extra $90, an 80GB hard drive for $99, and a 1.86-GHz processor for $190; or you can shave a bit off the price and the weight by ordering a 14.1-inch screen and a hollow travel module instead of an optical drive. Bluetooth and software cost extra ($49 for Bluetooth and $125 for Microsoft Office Basic Edition)..
