First and foremost I want to thank the Pew Internet project for collecting and disseminating information about ebooks and reading. I love the data itself, I just always want more.
Then we also have data such as "Among Americans who read e-books, those under age 30 are more likely to read their e-books on a cell phone (41%) or computer (55%) than on an e-book reader such as a Kindle (23%) or tablet (16%)." That makes me think about how many students I see on my campus walking around with devices, they almost all have smart phones now, but when I ask them about their own devices, they almost all have computers, but only a few have ebook readers or tablets. So, I'm not surprised at the numbers that Pew found, it seems relatively reflective of readers and tools that they already have. I do think that as prices for thing like tablets and ereaders drop, that these numbers may change. Right now I'm waiting for information where I'll be able to purchase the Txtr Beagle, it seems to be a bit limited as a reader, but the estimated $15 price and smart phone tie in may it become an effective school accessory.
As for the part on ebooks and library use: "Many of these young readers do not know they can borrow an e-book from a library, and a majority of them express the wish they could do so on pre-loaded e-readers. Some 10% of the e-book readers in this group have borrowed an e-book from a library and, among those who have not borrowed an e-book, 52% said they were unaware they could do so. Some 58% of those under age 30 who do not currently borrow e-books from libraries say they would be “very” or “somewhat” likely to borrow pre-loaded e-readers if their library offered that service." - I'm not surprised. I often do presentations to teachers and others about ebooks and I've seen the same kind of thing from my audiences. Many are just unaware of the options that public libraries today offer, not just options like ebooks and audiobooks for download, but also the classes that are taught there, the meeting rooms, and a large number of other services that most public libraries offer other than checking out books.
