Anonymous Kindling

Following my post about Charlie’s Brooker’s views on eReaders, I got this lovely email from a reader:

Reminded me of the strange phenomenon I observed in Japanese bookstores….
Without fail, and I really mean without fail, every bookstore… when you purchase a book, the attendant at the point of sale, will fit an opaque dust jacket, providing you with ‘paperback camouflage’.
I reckon the kindle and the ipad are going to be big in Japan.

Why the dust jackets? Anonymous reading my wife assures me… is culturally very important..?!?
