Most people use their mobile primarily as a phone or email device. Most people will always prioritize those functions above web surfing because they will prefer web surfing on a PC and are usually near one.
And why would you want to deal with all of the zooming when you can just have a monitor? I mean, it's great when you're on the road, which is maybe what, 5-10% of your waking hours for the average Joe, but at home?
I don't buy that at all. What about people stuck on a train? What are you going to do? Surf the web on your iphone.
What about if you're waiting in a dentist? You're going to whip it out of your pocket, and surf. Yes, compared to time spent at a PC, this is a small amount of time. But I'd bet the usage on the iPhone is the browser, then email, then phone/sms (With games+music in there somewhere).
I don't even think young people use their phones as phones (voice calls) very often now (UK anyway). It's all sms.
Of course it won't replace the laptop, but it replaces a lot. It's much easier to wake up, pick up the iPhone and check a few sites, than get on your laptop.
I agree about the zooming to a point, obviously if there was a hologram projector or something, it'd be great. But the scroll/zoom works for now.
I surely wasn't suggesting that nobody will ever browse from a mobile. Just that it will remain small potatoes relative to non-mobile for quite some times, especially in terms of profit.
