Bigger is different; or Jobs and Gutenberg in the same sentence?

It still astonishes me that people (moi included) can get into heated debates about the shape of a product that Apple hasn't even says might exist. But here is one more example: Apple Executives Share Thoughts on e-Book Market, iPhone Profits - Mac Rumors.

One issue in dispute is whether a "super-sized iPhone" would be any big deal. I say "Yes indeed."

And screen size 3-4 x current would do it.

A quantitative change (larger screen) creates a qualitative change --- it allows the one thing an iPhone doesn't: easy reading of long-form contenti.e. books and long articles. 

(And yes I have done my share of reading on an iPhone -- an entire book in fact -- and while it is not bad, it is not a game changer as might an iTablet.)

My guess is that Jobs would like his name to be linked with Gutenberg's as a major cultural figure (and who wouldn't?) and that is not a far-fetched goal for him. A device with a screen 3-4 times larger than an Phone (but with few or any additional features) would be a profound societal game changer, transforming so much it's hard to know where to start.
