Since your posts in general seem to indicate that you're logical and literate enough to know that what you posted above in no way follows from what I said, I can only figure that you are intenionally being difficult or unreasonable for some reason. You individual experience with the R15 is lucky, as is mine. Too many others have reported far more severe problems and our Illustrious Connected Moderator has reported that D* is aware of -- and is working on -- the most severe problems. Just in case I've overestimated you: Of course our software get updated. Issues with with minor features or fringe cases get through, get detected, and then, usually, get fixed. But if the software didn't do what it was sold to do, and we kept the customers money anyway, we'd lose the customer and maybe get sued.
