I hate to see the company fail consumers. There are those that claim that an Enterprise focus is more important, but ever since the iPhone, consumer devices have been leading the way the corporate environment. It's about mindshare, and folding up like this is just sad. Build momentum on one side with Xbox (the One X apparently has decent pre-orders) and Surface, but deprecate you offerings by abandoning the Disney Movie integration, Groove Music, and mobile in general.
Satya claims its about seeing tail lights and never being able to keep up, but the answer is never to pull off the road. Apple was dead, and could never compete with MS in the 90s. If they gave up they would have never seen the success they currently have. Backing out of a business is a cop out, and leaves loyal users without a path to stay the course. I don't expect that Windows Mobile would have been at 20% now, but after the Nokia deal they could have pushed from 3% to 5% in the US. They had double digit market share in some countries.... It was a conscious effort to put zero dollars into marketing and letting the platform completely fail. 5%-10% of 2 billion users worldwide would be 100-200 million users. Hundreds of millions of people could have been using Cortana, Bing, Skype, etc, but that was deemed too much of a monetary drain.
I think MS really needs to split like HP did and have a cloud/Enterprise team, and a consumer focused team lead by Panos. Gaining mindshare cannot be an afterthought, it needs to be a focus. If not there is no reason to support this company.
