I use smartboards every day for IT training (Staff and Students at University) and it’s extremely useful, not only for being in front of the class rather than behind a desk, but also to allow me to interact more.

I like the fact you can write on them (a live PC screen) to highlight & emphasise then save the results and send to the attendees to help aid learning.

I did like Russell Prue’s idea (at the #jiscrscnw09 conference) of ‘flat’ smartboards as an interactive desk, and wonder why there are not more options for hinges that allow an interchangeable screen/desk.
