It’s attractive to think about tablets as big smartphones that
need to be sold in the same way, but at the end of the day they’re
just not. Tablets aren’t substitutes for smartphones, they’re
complements, and for a lot of people they’re a third (or even
fourth or fifth) mobile device, and expecting them to buy one with
a data plan isn’t realistic.
To subsidize (with carrier contracts) or not to subsidize, that is the question.
