The 10 GUI concept is nice, but it might not consider very well users with disabilities, and

has been pretty good on this.
The cloud thing is nice when it is free always available and secure, so you don't loose anything and get a lot. Sad and doomed to fail if it is ad based, as by what that patent shows. I hope it is not, it might be working for the mobile things that many are used to, and that we already have to pay to use them, the iPhone/iPad wireless data service but for a professional work/personal activity it needs to be seamless, and when needed fully operational when not connected.
The cloud thing has some limitation when you travel out of the country or out of the grid. Even nowadays many flights have an internet connection and most of the times you can find a connection it is still limited and will cost you extra to use it.
If they find a way to keep your stuff safely and perfectly available for you anywhere anytime, then the cloud will really work.
A much tighter security for whatever cloud thing they do, will be a key element in whatever "magical, revolutionary, whatever new word they use" next OS

releases.
I just hope that it is released sooner than what it took them to release the leopards.
They know how to make things change to the right path.
If you had been using

stuff for a while, you had seeing the different leaps made from the Apple II to Mac OS, multifinder, OS Xs, Leopards plus all the things they had done in parallel Newton OS, iPod, iPhone OS, iOS 4, you know what I mean.
