I'm sorry, but just because the mount isn't good--doesn't make sense to have to downgrade to one of the entry level endpoints. Even if the quad cam wall mount was actually mounted to a wall the safety tabs still don't work and pop out with slight tension.
Cisco should be revisiting how customers are using their products. Another example is the poorly designed MX300 back cover for the wall mount. What logic would it make sense to have to pull the unit off the wall just to access the cables. That back cover should have been able to come off independently and not require 2 people to service the unit.
