Doesn't work like that. You switch between OS by pressing a button. It switched between the 2 OS is a matter of seconds. You don't turn off the device and reboot.
I would have jumped right in with this device (though I probably would have gone with the Samsung Ativ Q). I already have many Android apps due to having an Android phone. But I also have a PC with plenty of apps on that too (Steam being a good example). I would have dearly liked a dual OS tablet hybrid.
