Again, my deep conviction here with the OS of this device is that it will be a hybrid. It's not going to be a desktop OS converted for tablet use and it's not going to be a giant ipod touch. It will have feature and abilities similar to both types of systems yet be none of them.
It is going to be able to run desktop like applications with the ability to open desktop files but the interface for the apps are going to be different.
Likewise, iphone apps will also be able to run on it but of course it will not exactly be the same....they'll run better.
You want details? Your going to have to wait for the debut......or the brave spy who leaks info.
I agree. The only it can possibly work is for OS X to branch into a new version. Anything else is a fail as weve seen with other tablets.
