Do they have MP3 players in those places? If not, then this does not mean that the analogy djgreedo pointed at is faulty. A meaningful statistic here would be growth rate, which for digital music was 40% from 2006 to 2007 (for example).
As for e-books (and this is 2009 data, from The Washington Post):

Ok, if the percentage of US adults who actually read is less than 3/4, then what you said is even less likely to be true, for US (at least), right?

As far as I can see, we are well on our way. Pretty nearly only thing I use paper for these days is packaging material.

Actually, they can. That the current crop of online shops mostly require credit card payments for each purchase does not mean it's the only way of doing this. You can have an account in a shop, where a parent transfers some amount of allowance, that the teenager then can use in that store.
