I also strongly suspect that many app store apps could be replicated as web apps given no alternative, and that mobile web progress (both browsers and frameworks) would have also moved much faster and be in a significantly more mature state had not most of the focus shifted toward native apps.
Often, I'd be willing to bet that the naysayers never used first hand an iPhone. I don't think I've ever been more awed by a single piece of technology. Not even my first laptop, a G3 500 MHz PowerBook in 1999 that had an AGP ATI Rage 128 Mobility, Firewire and a DVD Drive left me that blown away. Everything about the iPhone 3G was amazing, with most intuitive user interface for something so foreign. It immediately changed the way viewed information, my friends would joke "Ask the godpod!"
It was one of those things that despite the absolutely absurd amount of press coverage and hype, was justified and even then it might have been short.

They just weren't as integrated as iTunes.
