I am opposed to this device. I like going into bookshops and browsing around, I like the smell of new books, and books are a good use of trees.
This machine has no - for want of a better word- soul. You cant turn the page down at an interesting point, you cant scribble on it and make notes, you cant pick up a well used Kindle, with grubby pages and bent corners, and know that it has been read, used and loved by it's owner, because it has no pages.
Also you cant put them on shelves, they don't have interesting covers, and you look like a dunce holding a massive gray slab on a bus/ train/ plane.
Just my tuppence worth
