Huge mistake by that angry, bald fat clown and his clueless ilks...
...to ignore desktop users - you can do so at your own peril.
We are the cash-cow: we buy all the OS licenses which in turn also trigger Windows Server and MS Office license purchases too, together providing the lion share of all revenues, around 75% of all money MS makes (entertainment/XBox/whatnot all included.)
Centralized/integrated storage systems are being commoditized at an accelerating rate so while MS is trying to push Windows Server down into home environment it's getting squeezed in the server rooms, similarly to Office which is being replaced by online/free alternatives almost everywhere except business/corporate use (and online Office is almost as bad as MS' Office 365 when it's compared to Google's online offering, free or premium.)
You are playing with fire, dear chair-throwing beancounter.
I can tell you that if you take away our Start Menu (it's not so much about the button, it's the menu) just because some idiot with no taste at MS dreamed up some junk like the Metro UI on a coke-infused night (Can I place a bet on the disastrous VP Belfiore, running that 'wildly successful' Windows Phone project, who drove more project into the ground than anyone else, only to be promoted every time?)...
...well, then you will lose all of our upgrades, period.
By all means you are more than free to go off and chase stupid tablet users with that fugly Metro and whatnot etc but I am warning you, Mr Ballmer: DO NOT PLAY WITH OUR DESKTOPS THAT WE USE FOR WORK. Seriously, BACK OFF. NOW.
