I was under the impression that it didn't handle web browsing well. My only ePaper device was a Pocket eDGe, and it shunted any web browsing over to the tablet side. If I'm wrong, then bonus!

Still, I think some interface tweaking needs to be made for electronic reference books, on the actual devices as well as on the digital files. Ebook readers are currently optimized for linear novels, at least from what I've seen.
