Short-throw projector whiteboards at necc

These pictures are of the smart Board input panel, and the wall moun base for the projector. (You can see the tubing for the projector coming straight out from the mount.)

I was looking a lot at the newly released short throw projector / interactive White Board combos. Smart Board has one, the 6100, and Promethean had one also.

Pros / Cons
Smart Board setup has a complete speaker set built into the wall mount for the projector
Smart Board can capture external video through the board software (Anything you can plug into an AV input - Document cameras, cable tv, VCR, etc)
The inputs are not directly on the projector, but on a moveable input panel that is connected to the board. (The source selection can be done straight on the smart board)
The Smart Board projector has a mini computer built into the projector so you can operate the board without being connected to a computer and save to a USB flash drive.

Promethean's board has a height adjustable wall mount. (So a completely wall mounted board can be adjusted by a teacher to change height to student level, or for students with disabilities.)
Promethean's projector arm is mounted to the board, so when adjusting height, no calibration is necessarry.
Promethean does not have speakers currently. (They are working on it.)
Promethean uses the Activ software to run the board, which is in my opinion more difficult to use.
Promethean's student response system has a beta software product that can be put on laptops, and use the laptops as a response system without having a set of the clicker hardware.
Promethean did not mention if it could be run without a computer.
The price points of both units are around 4200$.
