Considering assembly time for systems, this is no place for last-minute shoppers. A no-nonsense site for buying desktops and HP hardware. A good site for customizing an HP PC, though there aren't quite as many customization choices for computers as at Dell's Web site. If you're an Apple user, this site can be a major resource for hardware and info. Dell is very flexible about computer configurations.
Site is decent for window shopping too.
Has a good reputation, but its software is for the serious propeller- head only. Offers gift certificates. Also has a search function for finding good prices for other gadgets on the Web. It seems like obvious good sense to buy software and hardware online. It's a pretty overwhelming experience.
