A great piece, read to the end, on why we the Boomers need Big Things (not Blackberries, for example). Of course the "tablet" idea has been around for ever - but now we are squinting it makes more sense.

...a larger-form factor device would offer Boomers a bigger viewing screen and “lifestyle” settings, like fatter keys and a more forgiving keyboard to ease input, and wizard-like shortcuts to simplify recurring tasks.
This is key, because with the onset of age, Boomers’ motor skills have become less precise; their vision has become poorer; and their eyes get tired easier.
