Oh? I recall learning many things on my phone. How to launch apps. How
to use the task manager to switch between running apps. How to enter
text in general and swype in particular. How to pull down the
notification area and how to push it up again, etc... If you were
watching over my shoulder you may have said "Fail Fail Fail" many times.
Perhaps you would have been correct, the usabliity could be better.
However, it's easy to forget the first few times you satisficed through
something compared to the hundreds of times you've done something after
you mastered it.

I believe the following are tasks indicative of repeated and experienced
usage, not first time usage:
 * Changing the background image and setting in general.
 * Adding a game to the launcher.
 * Rearranging items in the launcher.

And these were some that users had the most trouble with.

Cheers, Rick
