I'm amazed people these days still think Microsoft has some sort of business model problem. Yes they've had a lot of failures, but even with those they've still got plenty of money and a huge market share, and they're willing to try different things out.
Developing products that are outside its revenue focus is called research and development, which they're really good at too, they have some super smart people up there. It's easy to pick a handful of things and poke fun at it, carrot top makes an easy living from easy hanging fruit.
Seriously, they're massively successful. I'd be insanely happy with a fraction of one percent of their success.
Though no doubt it'll get a lot of blog traffic, microsoft, apple, etc all are good for traffic spiking. just have to look at places like engadget for that. There are a lot of people that can ride on the back of a beast as big as them.
