I have to admit I'm confused about Google's mobile OS strategy - it seems incoherent. Are they going with a tablet with Android or Chrome OS? Or maybe both? This bit from Ray Ozzie helps explain.
According to Microsoft Chief Software Architect Ray Ozzie:
Android is a bet on the past. Chrome is a bet on the future.’ Android is still about installing applications on a specific device. Chrome OS is designed for a future where everything is online, in the cloud.
