I am still looking through the Microsoft by-laws to try and find where they can't do both.
Growing WP can happen, but it is taking a ton longer then I ever thought it would. How they approach the Threshold update for WP, brand it, and get other OEMs to support it will show once and for all if MS can get WP over the hump and into double-digit % of worldwide OS sales. I suspect we will all be very happy with how this is approached. I vote we give this new alliance with Nokia handset division, a new CEO, and all the new OEMs a shot.
In the meantime, Android and iOS are where the sales and the money is, and it only makes good business sense for MS to take advantage of that. Get Bing services, MSN news links, One Drive, Word/Excel, Azure services, XBOX Music and all their other dozen or so properties on those OS's and stay a billion dollar company. Having those services on Android, iOS, and the professional leaning BB10 just makes for more cash rolling in.
Too positive? Sorry, just how I roll.
