It'll start with myself:

reading:
1. cropped areas of which PDF under acrobat X gets shown.
2. some white background-ed PDF, especially scanned books, displays tiny grey dots as its background
3. languages written vertically is awfully slow (eg. traditional Chinese)
4. dictionary needs improvement as the way it grabs word is awful, missing letter, as its position is annoying. M90 should be as least intelligent enough to position dictionary panel at the bottom each time the user flips the page, instead of top.
5. *Hide margins* should be seriously improved as well at *guessing* the margin as a lot PDF files don't have pure white margins but random funky symbols around texts, mostly residues of printing symbols.
6. full screen option should be memorized for each book.
7. more error tolerant of PDFs, as lots of PDF files ain't wired well, but M90 gives me blank pages
7. SPEED SPEED SPEED

web:
1. taking care of crashes
2. cookie issue

misc:
1. sleeping should consume little or none power, or as minimum as possible.
2. sleeping crashing is annoying
3. USB connection to computer is totally non-functional
