Marvell at the Future of Publishing Summit on Tuesday showed a prototype of a 10-inch tablet running Android. The example device uses a non-production shell but is expected to be fast, using an ARM-based Armada processor that could give it 1080p video playback without hurting battery life. The version on display appears to be using Android 1.6 rather than 2.0 or 2.1, but this would be more likely to change in a finished product.
