This looks possibly interesting - could be the best of BOTH
BBC News - Samsung Ativ Q tablet runs both Windows 8 and Android
It also runs using the New HASWELL chip too. Depending on the price I could actually get interested in this (Sorry Ms Surface I think you've just been "Samsung'd". The advantage of having BOTH OS'es is obviously clear -- for simple surfing etc I'd use the Android system - but for Business stuff including Ms Office I'd boot up Windows.
On these sorts of devices switch OS'es should be a synch -- instant on in both cases.
