The poster expressed the sentiment that the app store ecosystem is fragile and the income will end. If you believe that, investing in hiring more programmers for apps would be a move counter to your own beliefs.<p>Since I tend to agree with that assessment, I couldn't recommend doubling down on building apps.<p>There may be other good reasons to consider that, such as moving in another direction (consultancy, which raises the interesting question: is there a such thing as iPhone app consultancy?), but not for that reason alone.<p>Edit: Google says that there is such a thing. It strikes me as likely that would be more stable long term, and, potentially, even more lucrative.
