The way I read it, it seems that you have one hand below the table to turn the blade (with three fingers) and one hand controlling the wood and feeding it into the blade. Sounds kinda like rubbing your belly and patting your head at the same time to me.
It must be a lot easier to do than it seems.
The one thing I noticed was that it took a tool (looked like a nut driver) to change blades but, I'm sure that it could be replaced with a knob for just finger use.
Another thing I would like to see was the whole saw as it was being used. I haven't figured out the blade tension procedure yet.
I really expected that it would require special blades considering the adjustable stroke feature but, they said that it used standard (5") blades.
