Mobile platforms have gotten large enough that market share isn't necessarily a useful metric. There are many hundreds of millions of iOS devices out there. That's a pretty decent market to be addressing. (It also happens to be almost all of the top end of the mobile market, so an iOS only offering has a TAM of hundreds of millions of people who are more likely to spend money. Not bad really :)
