2 problems I see with this market: 1. It's getting smaller. Maybe not right now - I don't know the numbers, but I could imagine that as more of the developing world gets 'dumb' phones, the proportion of dumb to smart phones will actually increase. However, long term, it's a shrinking market. To be fair, you could say that about nearly anything. Eventually there will be a disruption or a move to a newer technology. In this case, that movement is already happening, however. 2. Will 'dumb' phone users spend money like 'smartphone' users? If the point is just to make your app/site accessible to those users and gain market share, then it may not matter. But if you want to sell them anything, it very well may. Regardless, the recommendation to "ensure that your web-based applications are compatible with Myriads [sic] browser" is sound and one we'd all do well to heed, if the market-share numbers make sense for you.
