It's finally out! Probably the most useful utility for Macintosh is not available for Windows at konfabulator.com. Konfabulator puts a bunch of "widgets" on your desktop that allow you to monitor critical system items and perform numerous tasks without having to open applications.
Check it out, I'm sure you love it; especially those of you with Tablet PCs.
Note: be warned -- the Konfabulator site is running really slow right not because of the number of hits it is getting.
