Personally, choice is better within the ecosystem. I'd rather not have MSFT take the Apple approach because for them to do so, they would have to have the infrastructure fully in place to do what Apple does best - offer a premium system wide experience. They are A LONG WAYS from that.
I looked to WP as the future when I came on board, where I can transfer one experience from one device to the next. MSFT isn't there yet, where my Xbox, WP, tablet and PC are really integrated. That's what I want to see. I mention that because it plays into the growth of WP.
What Apple does is that it uses its hardware and OS to fulfill one goal: have users consumer content, and be able get profits from doing so. MSFT isn't there yet, because Skype, Xbox, Office, and its other singular good services don't talk to each other well.
Why does that matter? Sony went to Android because that allows them to push the PS interests and ecosystem easier. Samsung figured out you need to sell more than just phones to compete with Apple, you need an ecosystem alternative.
So MSFT buys Nokia as it is the best and most easily brand out there. Smart move. But that will take take to integrate, just as it took time for them to fix the other problems in the OS.
To me, MSFT hasn't offered anything to other OEMs to make the OS attractive. At least with Android, an OEM can design hardware, skin it, and take their chances. Yes, HTC was the preferred partner in WP7, but the software didn't help matters in terms of giving them an opportunity to make money. Why do you think there is a Nokia Mix Radio service? Content for consumers, means they get more money from you. The phone is a one time purchase, content is multiple purchases.
Personally, each OEM should pick one or two features, build a complimentary system around that on top of the OS and it gives users a choice. I own both a 8X and a 920. If HTC decided that audio was going to be their thing, added better audio tech (assuming WP8 now can fully support it), build audio specific accessories, get exclusive content, and still put a dent camera into good design, they can get customers like the OP. Nokia's audio on WP isn't good, so that's an opportunity there. If Nokia continues to push mapping and imaging tech, they will always be the best game in town, even after MSFT absorbs them.
So I rather 2-3 OEMs pitching their unique reasons to buy their handset by still get that universal experience. More importantly, I'd rather the OS itself be mature and really make the choice about hardware preference than anything else.
