You should care if it takes them 6 more months.  They said in the shareholder meeting this was the week.    If you don't care that they keep pushing it out, well, no one else cares either.  At least thats the way it seems cause every time the date gets pushed back, everyone acts as if that wasn't the date in the first place.  Seems there is always another new trade show where all the deals will take place and the product will come out after that show.  The Japanese show wasn't it.  The CES wasn't it.  Maybe sxsw, except I can't seem to find them on the list of exhibitors;

Even if they are presenting there, and I "don't know where to look", it sounds like you are expecting another delay.  Thanks for the warning.
