Covered in another thread:
- More file format support; specifically, doc/rtf/html: easily-editable formats. It's a nuisance to edit epubs.
- Buttons, not touchscreens. Or in addition to touchscreens. I don't like having to smear the reading surface.
- Multiple types of bookmarks, even if they're just checkmark/dot/star--the equivalent of color-coded post-it flags.
- Better annotation/highlight support. Exportable as csv file.
- Ability to flag 2 (or more) books as "open right now" to switch back and forth between them easily.
- Side-by-side view of those two books, even if that means landscaped and only a few lines at a time.
- Better image zoom, including auto-captioning with the image filename and dimensions. (so when you hit zoom, it'd add "map01.jpg, 450x235" underneath it. You'd know whether it was worth trying to zoom.)
- Easy access to the book's metadata while reading it. (Quality of metadata depends on the publisher.)
- User-Replaceable battery.
- Solar charger.
- Tags/groups/folders editable from within the device itself
- Ability to see lists of both "all ebooks on this device," sorted various ways (title, author, date added, date last accessed, word count, filesize, possibly user-created rating), and subgroups--folders or tags.
I don't want a 9" screen. I prefer a 5" screen; although I can easily see the use for a larger screen, I'd much prefer better image/zoom support. I like a pocket reader; bigger than a 6" screen is a real nuisance for me.
If they ever figure out how to have a two-screen display that folds in half, that'd be great. Until then, I want small screens.
