Sorry but do you expect people who buy a Windows based smartphone to not know how the Internet Explorer icon looks, the twitter icon or the Microsoft Word icon? I mean people who are genuinely interested in this phone will know it's functions and I suspect that people with a smartphone will have a PC too, which means the majority of people who watch this add will be watching it from a Windows PC or will own a Windows PC, and will know what the icon's are about, Microsoft doesn't expect Apple shoppers to buy their phone.
I think the add is one of the best Windows have brought out, the Windows 7 commercial, that was very vague though. This was nice and clear -the man simply wants all his programs with him and the phone makes it possible. Can't be much clearer in my opinion.
