The Google Desktop team is pleased to release a YouTube gadget for Google Desktop. It plays YouTube videos right inside the gadget and shows a feed of the day's most popular videos. Please check out the official announcement on the YouTube blog.
Watching YouTube videos is a favorite pastime of mine while waiting for code to compile or team meetings to conclude. Now with this gadget, I am able to waste time more productively, as I can bring up the gadget in an instant and search for videos (hint: pressing the shift key twice brings up all your hidden Desktop gadgets).
Please give it a try and stay tuned for more new gadgets ...
