5. visibility (as noted by angrygoat) and browseability is terrible.
6. Flipping through an ebook looking for something is impossible.
7. Illustrations or drawings are rendered terribly.
The list of pros of ebooks:
1. It's just a better experience. Ebooks are lighter than their equivalent books, easy to use one-handed, fonts can be adjusted, you can carry as many as you want with no extra weight, you can search within a book, you have access with wifi to your entire library at any point in time without having to fill up a cramped apartment. Browsing for books to read is terrible, but I can browse at my local B&N and then buy the ebooks on Amazon (which makes me terrible, but what can you do).
In balance, this means that I've switched almost entirely to ebooks.
The objections that you give (1-4) are the ones that are fixable by hoisting the Jolly Roger. This a step I am reluctant to take but if point 1 keeps going in this direction, then I can't really convince myself that I can justify the cost. A literally out-of-print book  selling for $13 is so outlandish that it makes my head spin. A book where the e-book is twice as expensive as the paperback ? What on earth is going on here.
