There was a flurry of activity on the Notion Ink site,
http://notionink.wordpress.com/, over the last few days.
They are moving to Bangalore...
They posted a couple of emails from people looking forward to the Adam...
They hinted that they may have had something to do with the Google tablet (I may have read that wrong though)...
The app and content stores are being tested now...
Flash appears to be running with no battery issues...
They're updating their website...
Updates will be more frequent...
Although, nowhere did I see mention of anything resembling a release date. Not even an approximate one. The Adam really intrigues me and I'd if they get produced with the functionality they indicate I'll gladly get one. However, if this continues and some of the other tablets begin rolling out I'll most likely get the next best one instead of waiting for something that may or may not ever materialize.
I don't know that it is vaporware yet, but it certainly getting pretty insubstantial at this point.
