Re: The most screamingly obvious use for augmented reality...
Funny, because one of the reasons I like WinPhone is the almost complete absence of ads. Some apps have them, pay a bit and they are gone (or the app is removed).
Even the Facebook feed is ad free (a massive blessing even though I use it rarely).
I installed Words with Friends a while back because someone wanted to play - it started on iPhones I think. After a play, an ad plagues you. When I complained to the other party about this he said that the iPhone version played a 20 second video ad at you instead. They must be super tolerant and assume all phones are like theirs without even trying to find out, sheeple indeed.
Don't play that anymore, give me Wordament any time.
