A:AnswerYes. The Apple iPad cover is thin enough to use with the stand.
You can adjust the stand by using the well-made rubber inserts. You simply pull off the insert included on the stand and replace with one of the other inserts (in a small box that is included for safekeeping) that gives more room to hold the iPad securely in the base.
This also works for skins, rubberized and hard case.
You will have to take the iPad out of any very thick padfolio/kickstand type cases however which shouldn't be a problem, and just slide the iPad into the stand.
