Well, you also have to remember, some of those screens had to be simulated, cause you can't really have 'nice' video on video.
The one thing I will say, it depends mostly on conditions.
The iPhones my coworkers have, they are happy with. The thing I find funny is that one coworker has mentioned she gets better AT&T coverage where my company is right now, which is in Santa Barbara, a medium size town versus where she was, which was in the Bay Area, Palo Alto, to be more exact.
Palo Alto should have better, if not superior reception than Santa Barbara, especially closer to the Bay Area. But she said she gets better indoor reception in Santa Barbara than she does there.
What can I say but Your Results May Vary. The problem with Advertising is 'what will convince you more to buy our product.' And I am sure the flipside of this, there may be an iphoneforums.net or something retorting all the Verizon/Droid commercials and what not.
