I do have to admit, one thing that I read about Windows 8 that I thought was kinda cool is that programs can have Metro and desktop interfaces compiled into the same executable. With "dockable" tablets becoming popular, I could appreciate walking around using Metro and having my screen and running programs automatically flip into desktop mode when I got back to my desk. Something about that struck me as Amiga-like. In the UI Style Guide, Commodore encouraged developers to include Shell, Workbench/GUI, and ARexx interfaces in their programs, to allow users to work with whichever interface they felt most comfortable.
It was some time ago that I read about this feature for Windows 8, maybe even during the public beta. I don't know if it's still even true. It certainly doesn't seem to be widely promoted or encouraged.
Using a Win 8 touch screen device I groan now when I have to go back to the desktop. I used to curse "Metro" when I first upgraded my PC. Mouse = Desktop. Touch = Modern UI. Having your settings backed up on windows live makes moving between devices a consistent bonus. It'd be sad if Microsoft dropped it for the unchangeable masses.
Dockable is so old hat. Bluetooth 3 or Wireless U. The way of the future. Add wireless charging and whammo. There's a part of me that thinks if Jobs was still about the new iPad would have these capabilities.
PS: The ZX Spectrum app is fun. Can't wait for the Amiga one.
