Personally, I think the current Microsoft is quite alarming (and I say this as a .Net developer who relies on MS as part of his day job).
It's been pretty clear to me for some time that MS as a whole look at Apple and Google and realise that they done goofed - both with Xbox, but more importantly, their original goof was making Windows an open platform (in their minds, based on revisionist history)
MS now look at IOS and to a lesser extent Android, and see that both Apple and Google have MUCH more control over the customer on those platforms than they do on Windows.
So whilst MS seem to superficially be embracing Open Source on the development world side (which is a GREAT thing), this is at odds with what they appear to be doing on the gaming side, which is by any means they want to control the route to the consumer - Apple do it and make crazy bank, why can't we?
It certainly seems to me that MS want to leverage the Xbox Live subscription model for Windows somehow; they want the recurring subs, but most important they want that customer!
I suspect that they are 'casting the net wide' in this enterprise, they want to see what sticks; and for them I suspect that the 'Xbox Machine' is what they would prefer, because they effectively move Windows to a closed platform by the backdoor.
The one thing that we have to look at in history where Microsoft have already taken something that was free, open and monetised it and made it closed was P2P onlinge gaming, and we gamers only have ourselves to blame on that because we let them do it.
Just like P2P Online play, MS are banking that the masses are looking for convenience, first and foremost, but also a veneer of 'comfort'; if they can provide a software gaming platform/architecture that is both backwards compatible and future compatible, then colour me very concerned.
This is MS way to phase out Win32 IMO, and if they can migrate to a closed (or much more closed) Windows world then the happier they will be.
It will eventually backfire on them IMO; they need to look back at the history and realise that the PC and Windows got to it's position of dominance and ubiquity BECAUSE it was an open platform.
But of course the shareholders just see the 'Apple Customer' paradigm and rage.
