Watson is the coolest OS X app I've seen in ages. It's Ur-client for Web services, with pluggable modules — including Zip Code and Stocks lookup, eBay tracking, phone numbers, movie listings, und zo weiter. The individual UI-panes for each service are beautifully and intelligently laid out and realized. Go download it! (Or, go buy a nice Mac, install OS X on it, and download it!) LinkDiscuss
