- the price
- the improved screen
- the new typefaces
- the browser (compared to k2)
- new PDF features (annotation/highlighting, contrast adjustment, password access)
- PDF is still not good enough (need link support, actual PDF annotations rather than using sidecar file, reflow option, fit-to-page chops things off sometimes). Sony is much better, has a mode to make 2 column PDFs easier to navigate, etc. Copy them.
- Let the browser open links that want a 'new window' (ask permission if need be). Allow PDF download with web browser, at least over wifi. Consider adding audio codecs so you can listen to some web audio (live radio, embedded mp3 etc.), at least over wifi.
- document navigation is not good enough. Bookmarks are useless without a quick way to navigate to them (a feature missing since K1). They need to use the NCX TOC, the 'HTML' TOC is awful for quickly jumping to a chapter/section. Hyperlinks should be easier to navigate to. Need a Forward function (for recovery from hitting Back too many times, jumping more easily between documents, etc.). They don't need to wait for a touch screen to improve this stuff.
- allow nested collections to make the 'folders' people happier
- provide a way to add custom fonts
- provide a way to add custom screensavers
- stop using 'experimental' to describe features that are used to sell Kindles and make them official (TTS, web browser, image viewer, PDF), spend some time to fix some of the bugs.
- fix audible wifi download so you can get format 4 instead of Enhanced. There isn't THAT much darn space to waste, and I doubt I can tell the difference on Kindle's cheesy audio circuitry. Fix the playback quality to eliminate annoying dropouts. Improve audiobook navigation so you can jump to previous/next chapters when paused and hit previous/next repeatedly without it jumping back to play/pause right away each time.
- add ePub conversion to the @kindle conversion service. For extra credit, add native support to Kindle (even without any DRM support).
- make a deal with OverDrive to support a large selection of mobi-format books for library borrowing.
- bring mobi up to parity (at least) with ePub in terms of CSS support (setting right margins, drop caps, hanging indents, image placement, better table support etc.).
