OK people let's get serious here!
LOGIC:
-By the ad description, this will be something that will be very apparent to the end user and WOW them!
-It is based on HTML5 and web standards.
-Apple will "start" using their massive data center next year.
-Apple supports 2 platforms, the App Store, and HTML5.
-Apple is releasing the new Xcode 4 with possible HTML5 tools.
-Apple is rumored to be creating a open replacement for Flash called Guiandula.
-Apple is rumored to rebrand Mac OS X to iOS and iOS Mobile for the iDevices etc.
-This new feature will be at the very core of the OS. (Think QT).
-Nobody has done this before.
-Steve has said on several occasions that he doesn't think everything will go to the cloud or that we will use dumb terminals. (All things D several times).
NOW... Taking these things into account, my guess is that this is something where Apple will implement their two platforms within the Mac OS. In other words, Apple could somehow integrate the App Store with iOS as being integrated along with its apps, or as an overlay such as Dashboard. BUT ALSO & MAINLY perhaps the ENTIRE OS will be able to render HTML5 and web standards and not ONLY in the browser. In other words, you could have HTML5 apps running as if they are native apps right in the OS, no browser involved!!! NOW THAT would be VERY interesting and a HUGE threat to Microsoft and Google. It would be different than a cloud OS. It would be a hybrid of both and VERY powerful and versatile!!!
This is along the lines of what I see happening based on the evidence I compiled!
Anyone have some real or serious thoughts about this?
