I don't have an iPad yet. But my in-laws, my wife and my daughter do (all iPad 2s). I have a MacBookPro a Droid X and several PCs that I use for video editing with Avid. When the 4G iPad is here, I think I'll jump in.
In the meantime, I am busy helping my in-laws get their iPad set up and it has not been a piece of cake! See other thread for challenges.
