Plastic Logic will pull its headquarters from SV back to Cambridge to concentrate on being "a more European company", according to industry reports. My guess is that there were few takers in SV for their technology and the Russian investment didn't hurt. A trial run of 1000 paper-thin e-readers using Plastic Logic's technology and loaded with the required curriculum content (w/hyperlinks) have been distributed to Russian grades 1 to 6, according to reports. The hope must be to have Russian kids get used to portable electronics learning early in life (plastic screens do less harm than glass displays at that boisterous age). Apple should think about that.
