Here are a few thoughts. Probably not comprehensive.
- I don't like losing the physical buttons:
• Lack of page-turn buttons means I have to take off my gloves on cold train platforms just to swipe the screen.
• Back, Menu, and Home now take 2 taps each (the first one to display the options bar on screen) instead of 1 button.
- I sorely miss the ability to use the 5-way controller to jump between sections by clicking it left and right. That functionality is just gone on the PW.
- I also mourn the loss of the progress bar. The percentage display and "37 min left in this book" in no way make up for that loss.
- The lack of text-to-speech is highly inconvenient.
- I strongly dislike that the memory is so much smaller than the KK (feels like we're traveling back in time or something ). Now I actually have to think about which books to put onboard, rather than just loading every book I've ever found.
- The battery doesn't last as long.
