This is a few months old, so I'm catching up: 10gui is a radical rethinking of the computer interface. Rather than use in-air gestures (like Sixth Sense), which fatigue the arms; or imagine 3D interfaces to replace 2D windows (as I've been expecting any day now for 15 years), 10gui uses a 10-finger board connected to a keyboard. Gestures with any number of fingers on each hand have standard functions, and side edges for "global" and "local" menus create context.
After using my Droid for a little while now, a lot of these concepts make sense. Minority Report-style UIs have to hurt after a while, and I love the global functions on the Droid - the home screen, menu button, side swiping, etc. (To iPhone users there are nothing new; coming from a Blackberry Storm, a pathetic imitation of the iPhone, they're wonderfully new.) OSX and Windows have the same global spaces -- the dock/taskbar, top menu/start menu, etc, but there's something about the simplicity of a mobile device's multitasking (an advantage of Droid over iPhone) that beats the complex, randomly spaced windows we're used to, and 10gui moves toward that direction.
