New Kindle e-readers no longer appear on computers
(goodereader.com)
This is a most excellent place for technology news and articles.
I'm too lazy, I just borrow from the library and use them on the device. Stripping the DRM takes some level of effort, and I don't intend to keep the books anyway, so I just let the DRM do its thing and turn off the wifi so they don't disappear until I'm done w/ them.
Works fine on my SO's Kindle, and I'm considering getting a Kobo and hope it'll work there.
