Mine takes 2-3s to come up, and at that point switching inputs takes pretty much only the time it takes for me to choose it. So, again. The problem is not that it has to be below the OS. The problem are crappy OSs and/or hardware.
Input switching on my TV doesn't even cross the Doherty threshold, or at least not in any way that I notice. And believe me, I get as irritated as anyone with laggy TV menus - which is one reason I refuse to buy Samsung at this point.
