That's may be true, but that doesn't mean Firefox/Gecko isn't a viable alternative just because fewer people are choosing to use it. In fact, I think it demonstrates my point that people don't need competing browser engines that badly because they aren't radically different. There was a time where IE was hemorrhaging users to Firefox, but that was because Firefox legitimately did things better than IE/Trident. At this point, however, our expectations of what a web browser should do are fairly solidified, so people are likely going to choose whatever is being marketed to them the most and comes installed on many Android phones by default.
