How to Turn Your iPad Into the Ultimate Video Rig, article.
First, there are a couple of tools built into the iOS camera app you should know: auto exposure and auto focus. If you want to focus on something, just tap onscreen in the camera app, and it’ll focus there. If you want to lock in that focus, tap and hold, and the AEAF lock notification will appear at the top of the screen. The latter is particularly useful if you’re recording an interview, and you want your subject in focus for the entirety of a video.
I'm not sure how limited the video quality from a new iPad is, but if it's good enough for the purpose (and for web use it surely is), I very much agree that it's a very kewl device for the purpose. In the same slender package you have everything you need: the camera, the editing software, a big screen for the editing, and means of distribution!
By amazing coincidence, just before I found this article, I got a fresh comment on the last article I posted with a similar viewpoint, The iPad As Mobile Journalist Studio. And this one too.
