This is interesting. I currently have an SX600, and I'm honestly not that happy with it. Since I can't see anything, I disagree with the part of the video that talks about the touch screen. I can't use it, but luckily, it's not on the SX600.
The things that make me want a 900 are that it has most of the voices from the Genos, better speakers, a much better keybed, and the joystick. One thing I found interesting is that somehow, the SX600 has a few voices in the percussion and drums category that the SX700, 900 and even the Genos don't have.
