Why did you buy it?

I wanted a keyboard that sounded like a full-sized grand piano, with the action of a full-sized grand -- this one comes really, really close. The P90 is the best-sounding keyboard I've used, and I tested a lot of them before I bought it. Most people find it really difficult to tell the difference between this and the real thing.

What does it do for you?

It lets me play gigs without dragging around a grand piano! Guitarists have it easy, but if you play piano you've got a big problem. On the whole, digital pianos sound fake. If you're used to the real thing, you'll notice that a lot of keyboards have a really cheesy tone. The P90 sounds convincing.

Would you recommend it to others? Why?

In a second I'd recommend it. It just sounds amazing. The keys in the P90 are fully weighted. It's exactly like playing a very good grand piano. Inside the keyboard, there's lots of levers and weights that simulate the way a real piano's strings interact with the keys. Some purists will tell you that a keyboard can never match the sound of a real grand piano, but I think that Yamaha are nearly there.
