Yeah - Microsoft killed it with Word. Sorry, couldn't resist

Microsoft might be slow, but I think in this case the company has a holistic, logical view towards the computing patterns of the future, and it's software stack(s) are designed to address the future (not just the present). Yes, this means the experience is very different for users on non-touch devices (it's fine for use once you get the hang of it, and I do actually find it quicker in most areas with keyboard and mouse than the old desktop / start menu environment), but those devices aren't the future. Yes, they're not going away, but they're not the bulk of the market, and their usage is diminishing in usability versus smaller, more portable devices. Also, and on point, Bing isn't a bad search engine, and it's not just a competitor to Google - it's technology is behind more than just Microsoft's search. It's used (obviously) to sell advertising, but it also can be used to design and tweak Microsoft's own search engines in products like Exchange and Outlook, Windows itself, SharePoint, etc.
I think Microsoft actually has a winning strategy for the future, even if we can't quite see it yet. The future of computing (say, 10 years from now) is going to be devices, services, and "cloud" storage and computing for the vast majority of consumers and small to medium businesses. For the large businesses, Microsoft's products can easily be tuned to accommodate "private" environments (they already do this), so that there will be choice there.
Will it actually be a winning strategy? I honestly don't know without a crystal ball, but it does seem like there's been a lot of thought and planning into the products being released this year and next and how they all sort of just "go together". It's a bit difficult and premature to look at the forest they're trying to plant today and say what kind of growth it'll have, but again, this will be something we'll revisit in 7-10 years and see whether or not this strategy has resulted in a growth forest or a forest fire
