Google just announced Google Gadgets for Mac. I don’t understand. The standard way to get dashboard widgets is to download them from wherever (direct from apple or just direct from the developer) and install them.
Google’s way is to install software that I don’t need (google desktop) in order to browse their library of widgets.
This has happened a lot recently. One of the big reasons I went back to apple’s Mail.app was because google notifier required some crappy Google install program.
