The only reason I own a 4 is because it was bought for me. Otherwise, the price point was high enough, and my old 2 was "good enough", that I just didn't see the point to upgrading that often. It's not going to compete with my phone upgrades. And I suspect repeat customers would have to be a significant portion of their business sustainability. I imagine now or sometime last year would have been about when I naturally would have upgraded, and I suspect if I had seen a ton of reviews favoring cheaper models from competitors, I probably would have jumped ship.
