thanks.
I figured I'd be able to view the toc and calculate how many pages are left in the chapter. Had to do this when I was using ereader on the iphone.
Stanza will tell you what page you are on in the current chapter simply by tapping the screen, which while maybe sounding superfluous, is actually quite a nice feature. Though the absence of this feature is certainly not a deal breaker.
The 'Read' indicator, again, is just nice to see - gives me a sense of accomplishment when viewing my library.

But again, obviously not a deal breaker.
I have question regarding Collections:
I would use this for grouping books in a series. When I create a collection with the sony software and add books, how does the sorting within the collection work? Can I set it to custom sort where I pick the order? Or are you stuck with alphabetic?
