I just took a look at one of these. Neat! Instead of sliding along a couple of bars, the miter saw glides very smoothly along articulating joints. Pushing the blade cartridge sideways didn't seem to have any effect, unlike my Kobalt which deflects a bit under just a little sideways pressure. (My first thought was "I bet that eliminates that problem.")
I wasn't able to get the tilt controls to work, but since it was a store demo that I was just looking at, I didn't try too hard. They're located on the front of the saw instead of somewhere on the back.
It looked like the motor was belt driven, so it should be very quiet. Interestingly, the blade guard has wheels on the front which means it will slide along the work. This allowed the guard to be all the way down on the table while moving the blade.
