Not stupid at all. The Android OS drew the spotlight with its gigantic market share increases mostly because it started from zero a couple of years ago, was pushed by the seemingly almighty Google, and it was to be either fast growth or death. It turned out to be the former, but the saturation point, where the competition will push back, has been reached. 800% market increase is not even mathematically possible anymore.
But all this talk about the share of certain OS (or platform) in the smartphone market is more of a cheerleading internet competition. The actual players and their weight is not anything like what it looks like at first sight. The Google Android project, even with the acquired market share, hardly brings any profit to the company. A recent analysis in Fortune magazine ("Is Google Over?") points out that out of the multitude of projects, Google still lives mainly on advertising revenue through its web searching engine. Everything else accounts for a minority of their revenue, and much less of their profit. Android was singled out as one of those very hyped venues that bring little to no joy to shareholders. Google are more and more turning into the good old one-trick pony called Microsoft.
Anyway, not to go off topic, Android by itself is not profitable. It is obviously a sponsored by Google project that is supposed to increase the reach of their advertising in the mobile space. For now the winners are mostly the hardware manufacturers - LG, Samsung HTC, etc., which make the phones powered by Android. The same will be true for the Windows 7 platform - Microsoft will be doing the Android thing that Google did, and they will surely gain some market share, if the same manufacturers embrace them. In the end both platforms will hardly bring any true profit to their sponsors, so it is not impossible that they might be abandoned, or remain a niche market, or branch into OS-s of the respective manufacturers.
Nokia, Apple, and Blackberry, on the other side, are different beasts - they have the whole cake and eat it too. Nokia got dragged a little behind by their blind faith in hardware over everything else, but they are coming back online. RIM retreats, but don't seem to be giving away easily their traditional highly profitable core business. Apple seems to turn into gold and sell at jewelry prices everything they touch, and the mountains of cash will surely help in their search of new big hits. And, very importantly, third party developers are getting a lot of that cash, and won't abandon them.

, I agree with the article that the Verizon iPhone will be the Android killer.
