eStation Zeen / Zeus from early August. If so, that'd make this touchscreen an Android 2.1 tablet with "significant" Nook integration for e-reading. Guess we'll just have to wait and see what's under the hood, software-wise. What say ye, HP, how about throwing us a press release yonder?
Update: And just like that, the printer has disappeared off the face of the internet, without so much as a cached Google page to its name.
Update 2: A trusted source tells us this printer is indeed the eStation Zeus of yore.
