If anyone has paid MSRP for a book in the last ten years, they're a fool (OK, maybe that's a little harsh but you get the idea) or they have enough money that they don't mind wasting it.
Or, they shop at their local, independent bookseller(s), the ones that can't afford a discount on every item.
As for ebooks, I'm a recent convert to them (February of this year), and I've been noticing a lot of problems with each and every ST ebook I've bought so far (all ePubs). One problem that's common to all of them (ST only, though) is that the margins are preset measured in ems. This means that as you enlarge the font in ADE on my ebook reader to a readable size, you also enlarge the margins so that it is unreadable--just a narrow column of text. However, because I remove the DRM, I can read it in the CoolReader software, which ignores the built-in margins.
I've also noticed the problem with ebooks having hyphenated words where the hyphen crosses out an adjacent letter--not always, but often enough. Until this thread, I had always assumed that it was a bug in the CoolReader program; now I realize it's a problem with the ebook, not the software.
I also have bought two ebooks that have no "real" cover. One of them,
Martyr (NF #5) I don't believe was available in ebook format (definitely not ePub nor Kindle format) until this year. Now I've learned that that newness is at least part of the reason for the lack of a cover. Does anyone know when the
Millennium trilogy omnibus first became available in ebook form, as that ebook also doesn't have a "real" cover?
To summarize, it looks to me like I came into the ebook world at the wrong time. That said, I definitely won't give them up, if for no other reasons than the enlargeable fonts and not having to hunt around for an out-of-print copy.
