TTNavigator on IPad

Question

I want to start using THree20's TTNavigator in my app, however I read here that it shouldn't be used on IPad.

I don't really get the explanation, and what using url browsing mechanism has to do the with the IPad screen size.

Did anyone encountered problem with TTNavigator on IPad ?

I don't want to start using to later find out I have problems running the app on an IPad.
