I agree with much of jragosta wrote above.
Time for Microsoft to do what they should have finished when they started Longhorn. A complete rewrite of Windows as UNIX-based. That whole NT kernel should be allowed to whither and die, taking the registry, scattered .com and .dll files with it! Packages: novel (for MS), yet efficient and easily managed by every single other OS on the planet. Continue to support Win7, 8 and possibly 9 (next year release) for another decade as they've done with WinXP.
How parallel to Apple if they did that*, considering it would take all of their engineering muscle and talent to have something ready in a couple of years, at which time... get ready for it... Windows X...
* They won't. Nobody with balls... including "___mer" all these years.
Scott Forstall: save him for a rainy day at Apple once he's grown up and seen "The Light"**; or if TC ever gets tired of all the BS the media and WS constantly throws at him and walks.
** Edited to add: "The Light" being iOS 7 and SF being humbled that some one other than his majesty could create a compelling modern OS. SJ experienced the same... whether he would ever admit or not is another story.
