Windows 8 with mouse - is that difficult

I am using Windows 8 for at least 3 months now. And I find it very difficult to switch back to Windows 7. Thats just because of sheer speed of Windows 8.

I use it with mouse and keyboard (yeah no touch) But it feels very easy with these traditional input devices. However people out there really shout too much about killed productivity with mouse and keyboard. So I just prepared a 5 minute video to explain the same


So, what people think here?
