It's fun to watch. I like playing digital grand piano, and it's fun to see what might be in the pipeline.
If my mind were more flexible at learning a new OS, I wouldn't be so dependent on Yamaha.
Speaking of portable grands, I'm thrilled with the Roland FP-90, and as I love the key feel and use it with Pianoteq, which is always improving, I'll never have to buy another digital piano. Home use only for me.
