I find places like doctors offices aren't a good way to introduce the edge. When I was bringing mine to PT I kept getting asked "Is that a Kindle/Nook/iPad/iPod?" (sadly, not joking on the iPod one-someone actually thought my edge was an iPod). One person wanted me to explain to her WHY she would need a tablet. In my experience, these kinds of questions equates out to "they wouldn't know what to do with this thing".

On the other hand, I've been showing mine off at the office and that seems to have generated some interested. Even had one colleague tell me he wished he'd bought something like the edge instead of his iPad. I'm hoping to go to a big conference this summer, so maybe I can generate some interest there. Provided edge's are still available by then.
