Why the iPad is for old people? (Not the diaper, the device)

Various tech pundits have said that, the newly released iPad is for 'older people'. http://gizmodo.com/5458855/the-apple-ipad-is-for-old-people.

I'm trying to hazard a guess as to why that is so.

You see I attended this talk recently. http://www.upabangalore.in/mwiki/mediawiki-1.15.1/index.php?title=Jan_2010_talk. One of the speakers outlined the concept of Personas in design. These are dummy people, with character & quirks & needs & wants that designers setup & then test against. 

Who is the Persona numero uno at Apple? One Mr.Steven P Jobs. It is anecdotal that Apple builds what 'Steve wakes up and wants looking at his mirror'. Any surprise then, that the iPad makes the oldies happier than the rest? Or is supposed to? 

Do I buy the fact that the iPad is for oldies? I'm not sure I do. But this seems to lend credence to the beliefs of those who do.
