This Vostro 1500 Notebook PC is at Dell Small Business for only $549. However, if you downgrade its memory (RAM) from 3GB to 2GB, it drops $50 to just $499. It has a 15.4" display, a 1.4GHz Intel Core 2 Duo processor, 250GB hard drive, CD / DVD 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). You can upgrade most components by scrolling across the icons at the center of the landing page. Shipping is free; sales tax is charged in most states.
