I just got off the phone with Aluratek. They confirmed that the firmware update released on Friday did indeed add Adobe DE support to the Libre. The update includes DRM and reflowable PDFs.
I was caught a little flatfooted by this announcement. Like many people, I had assumed that Aluratek had simply rebranded the Ectaco Jetbook (which is itself a rebranded JCNIP M218). I was wrong; Aluratek had licensed the hardware and been developing the firmware independent of Ectaco.
As of this moment, the Jetbook does not have this
firmware update nor can it use the firmware. (I tried.)

I have a Libre, and I can heartily recommend the hardware. Newegg is currently selling it for $179.99, and I think it's worth it.
