My father has taken to his iPad and probably uses it two to three times a week which I consider a lot for him.  Today he presented the device to me and said he could bring up the keyboard and I confirmed that he couldn’t.  I poked at a number of things and when switching windows the OSK would pop up for a moment and I eventually got into a near-physical struggle to keep the keyboard on screen.  After poking around I found the problem:  The iPad was connecting to the Bluetooth wireless keyboard of my iMac a floor and a room away.  The war on cords took another casualty.
