Just about every day we're treated to claims of a device being the "world's first" or "world's biggest" or, indeed, "world's fastest." Typically we file these stories into the "world's least exciting" folder in our inbox, but in the UK, Motorola's advertising wing has really been pushing the "world's most powerful smartphone" angle for the Atrix. Sharp-eyed UK viewers (one of whom was kind enough to write in to us) aren't buying it, however, complaining to the nation's Advertising Standards Authority, the ASA. Citing the Galaxy S II, which has a 1.2GHz processor compared to the Atrix's 1GHz, the ASA has indicated that the complaint will be upheld, as you can see for yourself after the break. Now, it's looking like Motorola will have to come up with a new way to market the thing over there. We'd suggest "smartphone most likely to run Firefox in an overpriced laptop dock," but that doesn't quite have the same ring to it.
