Widget Watch: the Jack of All Widgets
The Jack of All Widgets widget could perhaps be better named as the Jack of All Searches. It allows quick access to what I would guess is around 50 different searches and services, including Amazon, gas prices, people searches, package tracking (including the only widget I know of that searches the USPS), lyrics, weather and more. It's description page at Apple's download site says it starts up Safari to display search results, but with my experience it simply starts your default browser.
The Jack of All Widgets widget is freeware and available from Apple's download page.
