It's a revolution because it's going to change the computer from a tech device into an appliance (in the same way that, say, cars became driveable by anyone thanks to starter motors instead of crank handles and the addition of synchromesh to the gearbox).

Nero fiddled while Rome burned. Maemo Software is fiddling with GTK vs. QT while Google bypasses it completely to write something secure, fast, and close-to-the-metal. And makes sure it will run on x86 and ARM for good measure.

Interesting times lie ahead, for sure.
