Well this company fills me with more hope than say
http://noteslate.com/ for fulfilling it's promises.
They have videos of the pre production models working, one of the founders works for Broadcom as his day job and it uses a Broadcom chip, plus other videos from partners who have had the pre production models look good.
Where as NoteSlate keep posting in bad English that they are a real company and they are working on the device it will be a writable 10" eink tablet for $99, in the mean time all you ever see is 3dMax renderings of a concept.
I know what you mean about hype, fingers crossed then they live up to expectation, if they don't they have kind of alienated all the people who are currently interested like the Arduino and Maker community.
