Windows 8 is good to go.  Literally.  The new Windows OS will be able to travel on a portable USB stick.  You will have the ability to use that OS on another PC.  It will reportedly work on machines that run older versions of Windows as well.  All of your apps and settings will transfer with the stick.

It will make work much more portable certainly.

But it also makes me think of the future.  Forgetting for a moment that PC’s more than likely have a very limited lifespan for the consumer market, it's not hard to envision a time when the guts of the computer are the same, but you will carry your “computer” on a USB stick.  A Mac operating system will run on the same machine as a Windows OS.

Technology may be a lot of things, but it is never boring and certainly never stagnant.
