You have to look at growth and future market share.
Guess who is growing faster than Android and Apple in many markets? With Nokia the Windows Phone platform can compete and beat Android where it excels...cheap ass phones. And they can compete and win on the high end (look at the Nokia 1020...no other phone comes close with the camera).
So yes they are afraid of Windows Phone’s growth and future. When you are a market leader you have to look at who your competition will be and not stay static. but the Android ecosystem is so fragmented they can’t really improve the customer experience as good as Apple or Microsoft can. I think the new cheaper iPhone has android worried to. But I wonder if Apple has the ability to pull off a cheap market strategy. They are used to targeting high end only.
I really hate what google has done to Youtube. Google keeps trying to get me to connect accounts. Sorry, not doing it. I had my youtube account long before my google one.
