It will be Elop, it was his bounty for gutting & delivering Nokia at bargain price...
...I'm telling you.
Unless, of course, the shareholders revolt due to Elop's utter lack of enterprise business experience - because enterprise is STILL MSFT's cash cow, make no mistake.
I think anyone with a clue about IT & architecture would tell you that MSFT is simply wasting incredible amounts of money year after year when chasing the ever-elusive consumer success - look at the revenues, their most successful product lines: they are an enterprise company, they have NOTHING to do with consumer products, NOTHING. Even their core OS product (Windows) is practically an enterprise desktop OS as far as sales goes, if consumers slowly drop it and switch to Android tablets, so be it - though it's absolutely astonishing to watch as the Ballmerian idiocy is actually trying to push W8's retarded changes first on the consumer market who famously *NEVER* switch from something that works to something that's new and would require re-learning a lot of things (as opposed to enterprises forcing such transitions as part of policy, training etc.)
As I recall a FT article put it the best way: the only successful consumer division is the Xbox one - but then take it out and your balance sheet barely even changes.
And FT actually didn't even mention what a disaster Xbox is 'til date, regardless of its newfound profits - 10 years and $3 BEELLION LOSS so far. Practically every consumer project was a royal fuckup during the Ballmerian "Lost Decade" at MSFT.
Again: MSFT should concentrate on SMB & enterprise markets - of course, they should include a mobile division to offer fully vertical solutions including phones and tablets, offering isolated work and private device areas (though Blackberry's Balance with BES10 free /BB10/Android/iOS/multiplatform MDM features are already far ahead of them) but it should stem FROM enterprise needs, it should follow their requirements, not the other way around, chasing el cheapo Asian customers for a one-time $20 or so profit on a Lumia, that's just idiotic and a waste of time.
And, along with a shocking handling of a transition (he really gutted Nokia's value by opening his mouth at least a year early) that's what Elop's big "expertise" seems to be, unfortunately.
