Do You Watch Instructional Videos?

I generally like to troubleshoot my own tech problems, but after downloading a new program the other day, an instructional video started to play — and I found myself watching the entire thing. As long as they're short, sweet, and informative, I have admit — I'm a convert!

I've noticed them on two sites I visit regularly: Google uses them on their blog when explaining new features and Apple also includes instructional videos for new products on their site. Do you find them helpful?
