Having read many of your posts I've found that security has always been one of your primary concerns in any operating system.
You also put stress on how we'll Windows Phone and Windows PC work together. What makes me wonder is that if security is your utmost concern, why do you use one of the most unsecure OSes like Windows?
Wait let me answer that. I use Android, knowingly that it may possibly not be as secure as some other OSes but because it offers the most functionality with a decent amount of polish, which is I'm pretty sure the same reason you use Windows.
Secondly you've always believed that Microsoft is the company that cares most for user data, and Google is evil. No amount of logical argument or reason has been able to persuade you otherwise. Maybe if you don't listen to us, a respected Mobile Nations contributor can help you out a tiny bit:

Also you seem to have very odd tastes, which is fine but don't impose them on others. Android Lollipop is now being praised for being one of the most beautiful OSes out there, and I can certainly say that it beats the crap out of most of the Metro UI, but again design is subjective and I'm sure some will disagree.
Samsung is not thinking of switching to Tizen entirely, and Google does still have a hardware division.
I know that you desperately want Microsoft to grow, and no matter how many services it has it has very fierce competition from all sides, to name a few Bing is challenged by Google, Xbox is challenged by PS4, and Nokia wasn't thriving as it is. So Microsoft doesn't seem to have an extremely bright future from the looks of it, because it's services are often outmatched in both sales(and often functionality) by competing OSes.
Year after year we hear the same thing, if not Windows Phone 7, Windows Phone 8 will beat Android, if not 8, 8.1 and then so on and so on...
In fact I recently came across a three year old post on Android Central about someone that said that Windows Phone may have a chance of success and could maybe beat Android, and look today Android has dominance over the market with extremely powerful OEMs to back it up. Windows Phone 10 will barely manage to even touch Android's popularity.
Android is in no fix today, Android is actually in one of the best places it can be, it has a huge dominance and it need not worry about sales as much it did a few years back. Google, and competing OEMs, are now having breathing space to fix long standing Android problems that put it way ahead of other OSes.
And any sane person would tell you that the overhaul from Android 1.0 to Lollipop, or even the overhaul from KitKat is bigger than any overhaul Windows Phone has received.
A launcher taps into only the homescreen, apps and maybe a few other thing.
Lollipop taps into everything, from the lockscreen, to the colors, the toggles, the icons, the animations, the application design, audio and tons of other stuff.
If you really think Android KitKat and Lollipop are so similar I challenge to tell me 5 things in Android KitKat and Lollipop that have not changed at all.
And if you want more insight into the Lollipop update, I can link you to some good resources.
