We have been playing with the Android prototypes scattered through the Mobile World Congress here in Barcelona. ARM had theirs running on one of their lower-end processors. No fancy graphics demos, no iPhone-style multimedia fizzbang, just a humble ARM9 processor in a plain white prototype "to demonstrate the scalability of Android" and serve as a "development platform." Our verdict: it works, it's fluid, but it's boring. Qualcomm's Android prototype, however, is a real beast.
