An open keyboard is only expensive in the short term, in the long term it is cheap. (Example below)

Tyros Open and Close.

Close.
Tyros 2 comes out, trade in Tyros for new board, (Expensive) Tyros 3 comes out, trade in Tyros 2 for new board. (Expensive)

Open.
Tyros 2 comes out, purchase software (And if required hardware parts) and your Tyros becomes Tyros 2, (Cheap) Tyros 3 comes out, purchase software (And if required hardware parts) and your Tyros 2 becomes Tyros 3. (Cheap)

Styles are very personal, so it is unlikely any manufacture can please everybody all of the time, but by using style conversion software, users can pick and choose, the downside to this is that most conversion is done on a separate computer and then tweaked once loaded in the keyboard, however if you have an open keyboard the computer is built in, and so you can do it all in one go.

To fully understand an open keyboard, you really need to own one or play one for a good length of time. However once you do, you will realise just how limited hardware based boards are.

Good thread this
