but I saw a 1Gb card for <$50 in the store just the other day.
Phew! That's what I thought, you see, if they're selling downloadable e-books for 7 dollars (sometimes more, occasionally less), adding the price of a card, even if it's a small one, plus shipping and distribution of those cards, might well make e-books more expensive than paperbacks... not a good start for the market to take off. I mean, I might still buy some, for example, for the simple fact that I find it very
difficult to get hold of English books where I live (Spain), but I'd have to cut down on the amount, that's for sure.
