Indeed the device screen does not get in your way, except after a reboot. I still use a home page concept and have linked the bottom right hard button to home in just about every device. I still do see a need to jump to the device screen, whenever I need to go to a specific device to do something special or debug. BTW - My .pcf is "activity based", so it is not easy for me to jump to a specifc device without going to the Device Overview screen.
