I would really like something that allows me to create quizzes. Three I know of:

Adobe Presenter: I don't understand the pricing, but I think it's pretty high. Also, I know Adobe loves Flash, but mobile devices often do not.
ActivePresenter: Seems to be poorly reviewed
Camtasia: might work

I also like Wink and XVidCap for the price (free) and because they work in Linux, but I think both projects have been abandoned since 2008.

I could probably do without something that creates quizzes, if the price is right.

Any suggestions?
