When I had considered the S900, I noticed the size is a bit bigger than the 3000, not really that much smaller than the Tyros 2, which meant I couldn't use the case I used on the 2000 and 3000 and would have to use the case I use for the Tyros 2. So, the idea of it being any easier to move around and fit into a car isn't really true.

I haven't yet played the S900 yet, I bet it's a killer. But, I know how much I would miss the 3-layered voices and touch sensitivity. Once you're hooked on that, it's really tough to go back. I'm thinking the organ sounds will be different between the 2 also, it was very noticable between the 3000 and Tyros 1, so I'm just guessing on this. It depends what is important to each player.
