Good points. However I think the "stay hungry stay foolish" attitude is appropriate here. Imo it will take only a few "success" stories on Android (or whatever) for the platform to catch on. Sure it seems difficult (recall the article on HN talking about dismal sales figures for a relatively highly ranked android app). But it's definitely possible. So I guess my original post was just hoping the author would be the first real success story on a non-iPhone platform.
