Wikipedia In Your Pocket, $99
An anonymous reader notes the announcement by Sean Moss-Pultz (Openmoko, Inc.) of a new geek device: The $99 WikiReader. All of Wikipedia in your pocket with no Internet connection required. Works in bright sunlight. 3-button interface. You can update the information in the WikiReader either by mail (they ship a microSD card) or by downloading a 4+ GB file.
Whether or not the hardware is derived from Wikipedia may not be the issue. You can't pick and choose what you've borrowed, and haven't borrowed under the ShareAlike license.
It reads like this:
"If you alter, transform, or build upon this work, you may distribute the resulting work only under the same, similar or a compatible license."
I think that's very much open to interpretation. I'd definitely call this product "building upon [Wikipedia]".
