Other burning questions:

· Using the SI example, how good would those sports videos look if viewed via an AT&T 3G connection on an Apple tablet?

· Would participating publishers shutter their free websites? Perhaps not, but companies might erect some type of pay wall, or greatly reduce the amount of free content available online. Then again, the latter might happen anyway.

· Do commuters want to lug around a large tablet in addition to a smartphone? A phone is easy to carry. A tablet, probably not.

· If publishers offer a tablet directly to subscribers, what would they charge? Perhaps a multi-year subsidized subscription plan would apply. But would you sign up?
