Dell Small Business again has a well-equipped model of the Vostro 1500 Notebook PC for only $549, likely through 3/19. It has a 15.4" display, 1.4GHz Intel dual-core processor, 250GB hard drive, 2GB memory, 8x DVD / CD burner, internal wireless networking, and comes loaded with your choice of Windows XP or Vista Home Basic (I still recommend XP, Vista has yet to be perfected). Most of the components are upgradeable, just scroll across the icons at the center of the landing page. Plus, shipping is free. Sales tax is charged in most states.
