New Kindle Paperwhite.
Pluses:
The display is excellent. Perfect, IMO, for reading (and since that’s much more than 99% of what I use a Kindle for, just about perfect for my purposes).
The size is very good. Easily held one-handed for long periods of time.
Does indeed appear to last longer per charge.
Waterproof (well, water resistant).
In the 32-gig version, much more room for books than my other Kindles.
Minuses:
Navigating to my library of books sucks a bit. Much less straightforward than any of my other Kindles.
No auto-orientation. Not a really big deal, but it is a minor inconvenience.
I have yet to get it to sync up properly, and navigating to :last page read” in other registered devices has yet to work.
Just navigating to a different page or location in a book is clumsy.
All-in-all, the pluses far outweigh the minuses for me. The negatives are themselves only minor irritations, and are few. The positives are all things I was looking for.
