While I understand that currency power can vary quite a bit and have a huge effect here (and I don't know if that affects you), I would say it's generally not a big deal compared to other costs.

But another interesting point is there has been suggestions that the subscription fee be much higher, rather than remove it. I am supportive of this. The reasoning behind this is it helps to filter off a certain class of developers that tends to pollute the app store. Part of it is due to the poor discovery facilities of the app store, but making it more exclusive does have it's benefits, and drawbacks, naturally.

I am starting out using Android (getting an HTC Incredible soon as well). If I can get things working well with Android and want to start selling apps and/or start a software company for mobile phones -- I will start out with Android. If things go well enough that I am capable of pursuing another platform as well, then I would do the iPhone next but only after Android success. If I were to fail here, I would stick with Android because of the flexibility and I believe there are more opportunities there. I don't see Apple's ecosystem allowing business software to truly thrive on iPhone/iPad in comparison to Android and others -- I also believe this is intentional.
