Of course, there's the portability aspect. but with something like this, if it comes to fruition, people could start using their computing devices more readily, which would open up for some very interesting uses.
Just my 2 cents ;-)
Of course, i realise that the iPad can take time to 'get ready' too, but it was a very generic comparison.
I've tried to dualboot Windows and Linux from time to time, but I end up never doing it because rebooting is a hassle. I can't imagine rebooting just to watch a DVD on my laptop.
Protip: never use VirtualBox's "save machine state and close" feature if you plan to dual boot like this. Its too easy to forget and boot to that OS directly next time...
