And I do agree with you Paul, I also think that native and web applications should work hand in hand, and if you got a content based application we could take use of HTML5′s local storage to download content into the local application. Like they were bridged togheter.
Task-based applications; in my view of point, can’t be placed on just one of those two options before you’ve decided what the application does. I think when the application strategy is developed; that is when you should decide weither it’s supposed to be a web or a native application – because some tasks could be web based and some on the other hand could be ment for the native part of the smart phone.
There is many questions and challenges when it comes to smart phone applications, but hey – that’s what makes it fun! :)
