Mine arrived on Friday. I confirm the goodness of the screen and, even without changing anything, the colors are much better than the Pocketbook Color. The Kaleido layer is also less visible when reading a simple black and white ebook, so the screen is clearer.
There are some light leaks at the top end but nothing too annoying. The main flaw is the slowness, in some cases really excessive. It doesn't usually happen but for some books it does. For comics it's good and, I confirm, also reading regular ebooks with color photos or drawings is much better than with a normal B/N ereader.
As for the fonts it is true, the ones provided by default are not great, but the custom ones are supported so it is not a problem. Rather than Kindle and Kobo it does not allow you to determine the thickness of characters, just a rough check between bold or italics, and this is a flaw.
I didn't still check TTS but in the PB Color it is good and it should be the same here. I still didn't try audiobooks nor music.
