When you look at the specifics of these products, you'll see that several are, in one way or another, mobile applications that supplement larger corporate systems. Gartner is predicting substantial mobile growth in the next 2 years - one doesn't even have to like Gartner to acknowledge this is a fact - but this growth is expected to run in parallel with growth in other areas.
Microsoft's BI stack is still on Gartner's Magic Quadrant (latest report, January 27, 2011). They're recognized both for back-end processing as well as data visualizations, even if MS isn't on anyone's quadrant on mobile development. Gartner reports that "the vast majority of organizations have yet to embrace mobile BI", but they acknowledge that will change over the next 2 years. However, business user data mashups and "self-service" BI (PowerPivot, etc.), a growing need, aren't likely to be embraced on mobile devices nearly as much as traditional devices. So once again, a likely scenario is parallel growth.
I have a great Android phone (the HTC Evo) and an iPad and I have a pretty good idea of where they're strong and where they're not. Sure, new ones will come along....but I'm confident in saying that no one is going to feel like they're clinging to .NET for the forseeable future
