I'll never get this point. Laptop - fine, yes, but a tablet? How do you chat, post FB status, or write an email from the virtual keyboard? It's painful. Especially if you are 50+. I don't see my mom or dad using these devices.
My grandmother is 90 and she does all of those things from her iPad. She's also almost blind and has arthritis, and yet she finds the tablet meets her needs - which mostly involve keeping track of her grandchildren and great-grandchildren via email and FB.
