I guess Microsoft's take on Yahoo's Konfabulator widgets and Apple's Dashboard widgets are gadgets. Microsoft Gadgets even. Sounds cute. It's interesting how the same "class" of app will run on the desktop, on the web, and on auxiliary displays. I hope regular folks will have some simple to use SDK or "gadget creator" program to quickly whip up their own creations. Speaking of aux displays - "SideShow" makes me think of the circus.
I wonder what the first ink-enabled gadget will be.
