I guess it would be like an OS that once loads and starts, will run forever. You can put your machine to sleep which will freeze the sate, and then bring it back on again and start processing instructions from where it left off.

But if that's the case then they'll have to think of ways to do e.g. OS upgrades - where you normally reboot to flush the old code out of RAM.

Or how will you recover if you load a bad driver end experience a blue screen? Normally you reboot to flush the bad state and start again.

Somehow I think you'll need a separate cut down immutable OS alongside the your System so that you can repair things or make updates to the main RAM/Storage space.

Or at least that's how I understand it..?
