Sure its missing www.slide2learn.net from its list of useful iOS resource sites
, but over 46 pages, this guide does give a very good overview of iTunes, adding and also creating content, and gives some device management scenarios on page 31 that should clarify these for many.
I hadn’t heard of the ‘Apple iPad/iPod Learning Labs’ (a Bretford trolley that comes with devices) before – perhaps they are USA-only? (As is the volume licensing – document should be marked as such).
