I don't think  Whothat780 is in any position to verify if these systems kinda work.  He does not work for PYR so he doesn't know anything about PYR and their R&D progress in anything.  So making statements like it kinda works or it doesn't has no value to any invester.  Let PYR tell you the truth about their progress not some gamoke who got burned with PYR and now is trying to get back at them.  R&D has always setbacks and needs more time to work them out.  I live it everyday as an Engineer in R&D.  The I-phone did not happen overnight and I'm sure apple had a number of setbacks before it offered it to you and it still has issues like all technical things.
