I start with MS way back in the DOS days....in face, back in the IBM days....we had a DOS from IBM and then the thing called MS-DOS. Then I struggled with every sad version on Windows that MS released and many versions on ugly PCs that various manufacturers. Sad sad sad. Somebody should get sued. Still. Anyway, my point is that iOS is dirt simply compared to that stuff. Just download the iPad manual and read it. You'll pick it up in no time as long as you don't insist on doing things they way you are used to. You have to accept the apple way. iOS is a simple, compact OS that doesn't pretend to be all things to all people. Nothing you can do about eyesight. I'm 55 and I see up close just find and have no problems with touch screens, even though even I don't like typing large amounts of text on a touch screen.
