Jan Dawson looks at the relative cross-platform development efforts of Microsoft, Google and Apple:

To return to the point that sparked this post, Microsoft clearly has the broadest approach to cross-platform development of the three, developing significant numbers of apps for its own platforms but also those of Google and Apple.

Apple, not surprisingly, does the least cross-platform development. It’s encouraging to see Microsoft’s broad support, particularly as someone who has an interest in what it does with Minecraft. I don’t think there’s any serious threat that they’d cancel it on other platforms, but they could always give it short shrift.
