SimpleTech's Upgrade Navigator
SimpleTech is a manufacturer of memory and storage solutions. (Browse around the rest of the SimpleTech site for more information about the company.) It also happens to be my day job.

Upgrade Navigator is SimpleTech's tool to aid people find just the right upgrade for their computer, camera, PDA, etc. I also happen to feel that SimpleTech's on-line configurator is superior to those of competing companies (Viking and Kingston, for example.)
