Jobs has also stated a belief in one thing, and then contradicted it later. Take the original iPhone screen size, for example.
Also, I think he was against stylus UI. Somehow, I don't think he would be pro for the compromised capacitive stylus experience you get on the iPad.
But yeah, iPhone screen size.
"If you expect the iPod to do video, you're mistaken".
"You don't need copy and paste if you do the UI right".

And this refers to the interface.
In the past there were touch interfaces that were fiddly and required a pen to interact.
Jobs believed that was a poor interface.
For example, the new Office 365 for Windows still has loads of awkwardly sized buttons and drop downs, making it difficult to use via touch.
Some reviews have pondered how seriously MS is taking touch interfaces. But maybe this is why the Surface Pro comes with a stylus...
A Pen is just an additional tool to make the tablet experience better in various use cases, just like a bluetooh keyboard.
Sorry about the nitpick, but stuff like this gets on my nerve.
