C. Enrique Ortiz is right. The same was true for fixed internet. Remember when you had to dial in to get a connection? And it cost money per minute of use? A fixed price is even more important for the mobile web as so many of the potential services rely on you being connected all the time.
Why? Because the thing about the mobile web is the same as for mobile TV: it’s not the mobility, it’s the fact that it’s personal. It’s your phone. It’s in your pocket or purse. It’s you people try to reach on it.
Mobile is personal. Remember that if you plan on building a Mobile 2.0 service.
