Yep, the G-70 has some cool features, and that's fine if you prefer the older Roland sound, but many of us have a definite preference for the sound of Yamaha, Korg or Ketron products.

I love Yamaha's smooth, detailed, balanced sound far more than what I hear from other manufacturer's instruments, which is why I have a Tyros4 (which also has very cool features not found on the competition).

Sound is still the deciding factor for serious professionals, sometimes even to the point of adapting to an operating system that may or may not be quite as flexible or user friendly as that on other brand instruments.
