I upgraded from the S900 to the S910, and I absolutely thought it was worth it.

It cost me $500 to upgrade, and I got a brand spankin' new keyboard with a warranty. I got the great screen. I got all of the new voices. I got the new styles plus was able to keep my old ones. I have all of the T2 styles that aren't on my S910. I have all of the T3 styles that aren't on my S910 nor on the T2. All of the T2 styles play perfectly in my S910. Most of the T3 styles do too, but some need a little bit of tweaking. The T3 styles would have to be converted using software and then heavily tweaked to play on the S900.

By putting some rubber pads on the music rest, the music rest can hold heavier books. That's another little good thing.

Congratulations. You didn't have to wait that long, maybe four months extra. Better late than never. Enjoy your keyboard.
