Just got mine as well. And same as you, I "jumped" from kindle keyboard to Paperwhite 2
Since I'm in Japan, my model has 4GB, so I get the same amount of memory as my kindle keyboard has, which is awesome since I like to load a lot of books ^^
I got it for 80$ as well, from
auctions.yahoo.co.jp. It's been used for 1 day by a Japanese person, guess they didn't like it. Japanese often don't, since they read lot of manga and tablets are much better than kindle pw for that. Besides, kindle cant load so much manga as it can books.
Anyway, I LOVE IT. I love the flash card feature, light, being able to change dictionary directly while reading a text. Now I can actually get Japanese to English translation
Also vertical text is fine! That was most missed in KK.
Next best thing coming is Goodreads support. Can't wait.
Enjoy as I will too
