So, how many of the Top 25 All-Time Paid apps have you purchased for your iPad?
I've got 13, though I no longer use all of them.
I only have eight from the list of free apps. Guess I'm doing my part to support the economy. ;)
Just go to the App Store page linked, and count the apps with Installed and Install buttons. If you are on the computer version of iTunes, look for Update buttons as well.
