As much as it pains me to toss support to the big guys, I fear that I must agree with them about "limited to supplied content". Since they are getting their actual books from the houses (and probably already in approved "e-formats") and then converting them over using publisher standards they could really be handicapped for print size.

It would not surprise met if the publishers had strict standards on media formats. That might be one reason there is so much small text. 8 point lettering looks much different on a PDA or cell phone than on any of the current e-ink readers but the probability is high that they are being looked at as the same thing instead of two separate beasts.

Now as for margins, that one I will lay at the feet of the Connect store for bad formatting that could be fixed. Well, assuming that also is not a stated display criteria from the publishers. Hmmmm, come to think of it, it could be. A huge margin looks a lot different on the Connect display page used for testing than it does on an actual reader. I would hardly be surprised to find out they never even looked at their format standards on the actual reader before sending them out.
