Made a change for a quick review of ebook readers to mention why some choose eInk over LCD screens and the possible problems of been locked to a single provider and limited book choice.
Also, the on demand book printing machine is something more book stores need to get a hold of. When I still bought books one of the main reasons I bought the majority online was simply lack of stock/choice in store. I'd much prefer to nip to a book store knowing I can get the book there and then even if there's a small print delay, especially if they provide a few computers to allow you to browse books that are available on-demand.
If that machine can help bring down the price of paperbooks by removing the transportation and storage/dead stock problems, maybe there's still a future for stores to compete against online stores such as Amazon.
If I were still buying paper books rather than ebooks and our local store had print on-demand, I'd probably have continued to buy from them rather than on-line. Sometimes there and then access trumpts minor on-line cost savings, which is why I like ebooks so much.
For reference and technical books where ebook readers are still not ideally suited (imho) it'd be an even bigger advantage. Besides, they can offer a coffee in their store cafe whilst you wait for your book to be printed
