Sales figures are interesting, but so what.
I do agree that eBook prices should be a lot cheaper, for the cost of the book materials, printing, shipping, handling, are reduced to almost zero.

In time I expect the costs for eBooks to get lower and lower.

I read eBooks before eReaders. Then they were just digital copies. I preferred then and still do, the "LIT" format. I read them on my computers.

I hesitated at first on the eReaders, until the Keyboard Kindle, 3G. The ability to be anywhere and get a book, or even Wikipedia sold me.

I still buy books in paperback. I can buy a new book at Walmart by a favorite author or a new author I don't know, for $6 or $7 dollars. I only do a few of those each year, mostly on the spur of the moment.
I can buy a used paperback or hardback at Amazon for $4.00. It won't be the first printing, but a couple of years later, most are available. I do this all the time.

If I am writing, which I must confess, I seem to have less and less time for, I prefer a "tagged" (book marked) paperback for reference. (I prefer a paperback over a hardback usually.)
I "tag", usually with a sticky white address label.and if there is a lot of references, I write in the front of the book a short index of things of interest.
After time, I move some stuff, memorable phrases or facts, to a collection of notes that I keep on my computer and also convert to PDF which I move over the Kindle.
