I like the idea generally, and it would probably be the first place I'd look - communities and such. The problem here is that the market isn't one that has necessarily _chosen_ to be a part of the market and wouldn't for the most part be interested in a community/forum/gathering place. I think a good way to think about what I'm looking at is medication - how many people are on medication? How many of those own Android devices - this is the number I'm looking for. People "on medication" aren't a group like "people who like skiing", and so mostly aren't to be found in online communities.
