The SX900 is NOT a Baby Genos....
that said....when the time comes the surprise will be revealed.
I think the SX900 is actually more of a "young adult" Genos. Trimmer, leaner, lots of the potential of it's much larger, family member. Not a step down, but rather, a step sideways for those of us who have no room, or need for the extra keys, and cherish the advantage of on board speakers to use in a professional setting that doesn't call for lots of amplification. "Baby" just isn't the right word for such an advanced instrument. Yes, the Genos has more bells and whistles, and some people need all that. I prefer to buy only the bells I'll actually use. It's not the best, if it's not the best for me, and right now - the SX is performing beautifully.
