Not sure what to tell you. I saw some GPS apps abandon the WinMo line and continue to support the iphone platform. Garmin for example now makes a phone that they market to compete in the WinMo market so they are trying the exclusivity angle that iphone used. And oddly enough, they are rushing into the Android market now too.

Yes, the lack of standardization of hardware, phone/data plan and varying performance from phone to phone is an issue too. How do you support when you have people complaining that the turn by turn spoken directions don't work on phone X? It is a challenge.

Free apps are something else. Often you have a motivated developer who wants to fill a need on a chosen platform and they have the skills to make it happen. They bang out something and it ends up as resume rodder, maybe gets published, maybe draws more people to the project and things run from there.

Different things motivate developers, money usually being the biggest. If they are successful on one platform they are dedicated to, sure, it would be great to spread to others.. if they can/want to. If they don't have anyone to work on platform X, they simply can't though. If lobbying them for a WinMo version gets you nowhere, see if they will share the source code. You can always try to learn to program, and work on it too. Never know, you may get a job out of it if you are good.
