IMO as computer technology advances as it has been year after year current technology which is still in its infancy will continue to escalate to better things leaving what is now behind including arranger Kb's, electronic musical instruments, etc,etc, and all things TECH in our lives as it stands now....don't be naive to think these small increments of so called advancements will even be around 10/20 years from now as we know it.
Enjoy whats here now .....stock pile it if that's what you need to be happy because it will quickly disappear for sure in the near future.The fun hasn't even begun yet ...the sad part most of us wont be here to see it or enjoy it.
