While portability is great there are many problems with tablets, usually reduced eyesight(certainly for me and I'm not quite retired) is an issue, and nothing is better than a big screen to help one see what's on it. It's for that reason that I don't like laptops either. Also, for some elderly people, holding a tablet with one hand and navigating around the screen with a finger with the other hand is hard to do when they are weaker and unsteady. Then you have a virtual keyboard to type on too! I just can't see most elderly people being happy with a tablet.
