Until there is a change in technology, 2 devices works best for me. Still waiting for something lightweight that projects straight onto your retina or perhaps a scroll type roll out screen. Then, a big screen and a single device might be an option. It has allowed me to get a Nokia N82 with great Camera, flash, 3G etc. and when push really comes to shove, I can leave one of them at home etc. 1 device stays in your pocket while you use the other one all seamlessly. Where's the problem. Zuber
