Totally agree, personally. Some people use the 3G for other stuff, but I only read books. Btw, purchased Google eBooks are not like PG, though, they are formatted like purchased Amazon and B&N eBooks.
"It's a generation behind the Nook Simple Touch, and integration with Google Books isn't enough to interest me given the awful or non-existent editorial oversight in most public-domain ebooks."
I'm interested in the new nook too. I saw it in the store, but didn't bother with checking it out. Next time I will. Integration with Google is also irrelevant to me, but access to Google eBooks (and all the other ePUB books with DRM via Adobe) totally matters to me, and this is why I won't buy a Kindle, yet.
When it comes to well-formatted public domain eBooks, I like Feedbooks.
