Good post.
I would like to add, (with the risk of being banned by purists) that most todays piano keyboards do sound better as the real thing,
as long as you have a good soundsystem.

Approx 8 years ago I would say only the kurzweil boards were spot on, but today all top boards have excellent piano sounds on board and are allways in tune, unlike the real piano's which frankly need tuning after each concert...

The only thing missing between the acoustic piano and digital piano could be character, but you only hear that if played solo.

The difference between the digital top boards is only a matter of taste , just like with the real acoustic ones...
You can't say anymore this one is better as that one.
Most of them are spot on and better in tune then most acoustics.

My opinion only ofcourse but I couldn't resist to comment on this one.
