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.
From O'Reilly Radar.
...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.
As such, the premise of them plugging away on tiny keys and peering into the tiny screen of a mobile device like iPhone/iPod touch is a non-starter.
By contrast, the Boomer Tablet offers a superior input, viewing and playback environment for accessing your iTunes library, personal media, syndicated content services, iPhone Apps and presumably, Mac Apps; something that the 70M+ Baby Boomers in the US who are aged 53-73 would likely find compelling.
