We have the S950. Had it for about three months when a Tyros 4 anniversary model became available..new floor model.

Since the purchase of the Tyros 4, the S950 has been in the case. The Tyros has been out gigging two or more times a month.

There is a weight difference between the Tyros 4 and S950...about 10 lbs I think with cases on each. If I was out gigging twice a day like Gary, I might rethink it...but.

There is so much more control of features on the Tyros, the articulated screen, sounds are wonderful...hard drive that has a great operating system so file mgt is so easy.

I've thought of getting out the S950 and dusting it off, but I always reach for the Tyros.
