exercise a little patience with Ink and this product works GREAT. printing is not supported very well, but functions. the glitches with Ink are actually Apple's fault, and hopefully apple will make Ink more robust. (issue is basically that multiple API calls to ink, immediately after each other, sometimes causes the Ink service to break the connection to Inkbook. this happens when Ink is parsing a previous pen stroke, and you begin a new stroke before it is done parsing.)
