What is best way to learn MAC and iPhone for seniors. Are there any basic videos. I gave an iphone to my father recently. Spent three hours on a remote call/showmyPC.com. But there has to be a better way. Need general finder/folders/address book etc. Checking with libraries and workshops but not many, Apple store is OK (he went to one), but intimidating and not structured. Those from other generations may need a different approach. Suggestions?
