I guess to add scrollbars generally serve the following purposes

• Incremental scroll (covered by kinetic scrolling)
• Reminder at where in a document one is (only shown with kinetic scrolling when scrolling)
• Jump to top
• Jump to bottom
• Raise awareness of being able to scroll
• Jump to approx area (In an alphabetical list, one could guess a name with P would be about 2/3 the way through).

Am I missing anything?

I doubt we will change Nokia's mind on kinetic scrolling. The problem with both is duplicate means to an end that either takes up a large amount of screen space or is only usable with a stylus. We've seen this with previous versions of Maemo which ran on devices with larger screens.

What we can do is come up with ways to solve the missing features of kinetic scrolling without hurting the user experience.
