Oh dear. Remember Motorola's advert claiming the Atrix was the "world's most powerful smartphone?" Well it's now been banned in the UK by the Advertising Standards Authority. Viewers complained about the misleading phrase as the Galaxy S II has a faster 1.2 GHz processor, compared to Atrix's 1GHz. Moto said it meant "powerful" in the sense it could drive various devices -- the ASA didn't agree, since the phrase was read out over the final shot in the advert, where the phone appears in isolation. It ruled that as such, the advert was misleading and can only reappear on UK TV with the contentious phrase removed. Armchair adjudicators can decide for themselves in the video after the break.
