No, really.

I think the new management at Microsoft is making a pretty smart break from the past. Bill Gate's MS was "Information at your Fingertips" and "A PC on every desk" and that was mission accomplished, though thanks to the WWW and Mozilla as much as MS.
Steve Balmer's Microsoft was... I don't know what. Developers, Developers, Developers, Developers? Open Source is a Cancer?
The new MS is announcing MS for All! Built native Android apps on Windows! Build IOS apps on Windows! Host Linux on Azure!
Lots! of! Exclamation! Points!!!
I don't think they're getting out of the Windows PC or DotNet business, but it sure sounds like they are taking them for granted.
Admittedly, Day Two of their big conference and they're grabbing all the headlines. The devil will be in the details, as always.
In six months, I expect clients will be echoing back to me, "But can't you run your Linux apps on Windows?" and "I heard you can run Macs on top of our Windows machines."
