How is that modded insightful?
I don't think anyone with a hint of awareness thought that Android sounded like a crazy project when they announced it. I think everyone who had a clue recognized it as a bold move into a new market that would make a big difference. And, lo and behold, it was.
Also, quite frankly, I find it amusing when people describe Android as "owning the market for mobile operating systems" because it's a narrowly defined definition of "owning the market".
Are they owning marketshare for the larger mobile market? Yes.
Smartphones (no, not feature phones disguised as smartphones - I'm talking actual smartphones)? That's debatable and hard to accurately measure (since so many Android manufacturers sell "smartphones" that are really feature phones running a smartphone OS). Entirely likely this one is pretty much a draw.
Tablets? Not at all. Getting crushed.
Are they owning the market dollars for the mobile market? Nope. That's iOS's crown. And, for many, this is what "owning the market" might mean which makes your claim incorrect.
The mobile market is actually quite complex with various facets and layers and "owning the market" is a claim that no operating system (well, neither Android nor iOS - the others don't matter any more) can make. You have to be much more specific in what you're talking about before you can say anything is being owned. Otherwise it's simply too vague a claim to be taken seriously.
But, back to the original point - I think the only people who thought Google was crazy for creating Android were blog writers looking to generate page views and controversy. Anyone with a clue saw it as anything but crazy.
