I see in the screenshot that they have kept the same bad font, and no mention of changing fonts on-device (just changing sizes and margins, which you can already do). Bummer. I realize I am probably in the minority about this, but better fonts and/or ability to change them is the #1 thing that would make me upgrade.
Right now I use a Calibre plug-in to copy all the cover images to my device and then I manually choose the cover for the book I'm currently reading. I LOVE LOVE LOVE this and having it automatic would be much better. So I am excited to see that. There is just something much more book-like about seeing the cover of the book you are reading as the stand-by image. They stole this feature from Kobo, but I don't care, I would love to have it.
I would be really surprised if they stopped using the IR touchscreen. It's so great that Kobo and Nook also adopted it recently.
