I send this off to
support@coolreaders.com (and completely forgot that the name of the device is "Cool-ER," not "coolreader." Oh well.)
I'll let you know what answers I get. In the meantime, if anyone else has answers, I'm happy to collect those as well. FWIW, I'm not looking at buying a Cool-ER; I believe I could get another PRS-505 for about the same amount. But not everyone has that option, or wants it. And I'd like to know Cool-ER's official answers to these, as well as the info that "we all know" because we know what company makes the basic hardware they're selling.
* Is there a user manual for the Coolreader, and would you consider making it publicly available so that people can understand the features before they buy?
* Does the Coolreader support folders? (If I create folders in the Coolreader, will the interface let me click through those to find the books I want, or does it just sort them all by title/author, and I'd have to remember what category they are?)
* Does it need or want software--is there an interface, perhaps some kind of library program that allows editing of metadata or sorting of categories, to manage books and move them from the computer to the Coolreader?
* How many shades of grayscale does it support?
* What DRM'd formats does the Coolreader support?
* Do any of the books sold at Coolerbooks.com require DRM software, or are the books sold there without DRM?
* The books listed as "Digital Editions"--are they ePubs, or PDFs? While both read about equally well on a computer, they aren't the same when transferred to portable readers; I'm much more interested in ePub books than PDFs.
* Is there a way to filter searches at Coolerbooks by filetype, to say "only show me books by [AUTHOR] in filetypes I can use?"
