its just a pity that B&N only have about 0.0001% of the available books (i,e. of those that have been electronically published in any format) available through their store, and what they do have are vastly overpriced. I'd still rather own a paper copy of a book and pop it on my bookshelves, but at the same time I would love to be able to start reading an e-version immediately hence my last book purchase went through amazon and the errmmm less than kosher e-version onto my nook while the physical ones arrived.
I wouldn't have minded paying a (small) premium for that, even though I think it should be done by default. I wouldn't have minded buying the e-version if the price reflected the significant savings of not having the expenses of physically distributing the books to retailers, the retailers mark up, the printing costs, the warehousing costs etc. etc.....but in the end, the paper copy was cheaper than the e-version!
It's sad really...all the out of print books that exist, all the various opportunities to innovate and instead we see companies driving themselves to the wall from greed.
