Did you just come here to stir things up?
Considering the post is less then 2 months old, I can't think Pioneer has jumped all over making usability complaints the top corporate priority, some of the bugs are actually a PITA but old.
Did you happen to notice the poster and what their user name was? did that look a bit familiar? 
These are known issues, and as far as I can see, nothing that hasn't been mentioned here in discussion, there isn't anything there that was never said over here.
Sounds like you just want to cause trouble to me.
quite the contrary - I have narrowed my search for a unit down to two units, the X920 and a competing Kenwood. I was just about to purchase the Pioneer (lots of sales at the moment) when I came across that entry on the Kenwood forum. The way it was written certainly seemed to be favoring the Kenwood - I was hoping some Pioneer owners would jump in here and defute any parts that may have been "over the top", so to speak. I met the Pioneer rep in a shop a few days ago, hence my leaning toward the X920. The main point is, what on that list is truly a "deal breaker", and what isn't. 
For example:
-no power on/off button - seems stupid, but can it be rectified with a switch in the glove box, or a firmware update?
-plot several points with VR? Neither can the 6960 - no big deal here
-only 100 POI's? How many speed cameras do you intend to pass?
-no wireless remote? yawn
-no 5.1? in my CAR? double yawn
-lack of dual-USB? snoozing still
see, all of those are pointless to me - I want see what is pointless to other owners, and what they like
