Widget Checks Your Apps for Updates

Here's something I've missed since OS 9: a wee program that checks if your other programs are up to date.

The App Update widget compares your programs against the listings at Apple, Version Tracker, and MacUpdate, and then offers download links to the programs that are outdated. It generated a few "false positives," but also reminded me of a number of programs I'd downloaded and then never really checked out.

App Update has joined the tiny group of widgets I actually use. Which ones do you like?
