e-Learning in your Pocket

Just downloaded the Howcast iPhone application. Very simply you access hundreds of user generated videos on various topics (some serious, some off the wall). The videos offer advice and guidance on a multitude of solutions from how to extend the life of your iPod battery, how to tie a tie (badly needed), how to survive an airplane crash, how to give a speech, how to cram for a test, to how to conduct research, etc. "e-Learning on the go" - is this the future of training?
