I hope you get your wish. It's a pain to feel you are 99% of the way, only to hit a roadblock.
Consider that, aside from the TC vote for iOS, there is still the large number of versions of Android hardware and OS releases.
Look at the limited number of OS versions and platforms that PTC supports for the rest of their software. That suggests a limited test and problem resolution budget, something all companies face. I can see why shooting for the iPad made initial sense. While the population of users is smaller, so is the variety to support. It may even represent a high-point. While Apple is sure to release a new device or OS version every year or so Android will likely see 100s of models with various OS versions, some customized. It might even pay for PTC to get a deal where the tablet ships with the software.
It could be worse. PTC could have release for WindowsRT.
