How wonderful that you have embraced technology and are obviously using it to your benefit Lon. I too marvel at all the things available to us and try to stay relatively current. I had an iPhone for maybe four years. Going from the Blackberry to the iPhone was like going from the 8th grade to college. When it started losing battery life too quickly, I got an cheap Android phone because I needed a phone fast, then upgraded to a Samsung Prime I got as a gift about 8 months later. I changed from Sprint to MetroPCS which I'm very happy with. I can get secure WiFi for my tablet using my phone when we're away and it costs nothing. I was told that it would cost about $10 a month with Sprint. BTW, I still have my iPhone. I used it for pictures sometimes and to listen to music since my classic iPod no longer works. I had gotten a Samsung tablet before I got the Samsung phone and I really do like the Android system. It took me a long time to be interested in getting a tablet. Got a real cheap one for sitting through a timeshare upgrade presentation. After about 6 months I wanted a better one so I could take full advantage of all the apps available, some of which are actual money savers.
Who would have thought when we were growing up that we'd be able to have phone conversations on the go (remember how futuristic it seemed on Star Trek?). Who would have thought we could watch T.V., load our entire music libraries and listen to music, order food and transportation, take pictures, receive mail, deposit checks, pay bills, buy groceries and play games from a phone! I'm just turning 70 this week but I hope I live at least as long as you so I can see what technological advances they will have invented by that time. I have a friend who doesn't even own a computer and has smart phones (gotten as a gift) that he doesn't know how to take full advantage of.
