1) Yes mobile moved the market by capturing hundreds of millions of people who would never have owned a computer otherwise, and Microsoft failed to react to this.

2) Do you have any data to back up the claim that mobile usage leads to desktop purchases? I have never heard such a claim before

Given that I see more Windows laptops and 2-1 devices than Android tablets around here, Microsoft has reacted quite well to this.

Additionally given the amount of people that run Office on their phones, in spite of total lack of usability to do such kind of work on those devices, again very good reaction.

The first point is anecdotal at best, the second point is moot since were talking about operating systems.

The anecdote is quite visible on any European shopping mall.
