This has been debated here before. There are so many different skill levels here on the forum, we don't need to have the real vs faker arguments again. Personally, I can play other instruments "for real". As has been said earlier, it's a tool that that allows you to do more. Similarly to Bill, with different details I moved from acoustic accordion and a drum machine, to midi accordion and sound modules, to an arranger, which allowed me to play more genres of music that wasn't accordion appropriate (I know a guy that plays Pink Floyd on accordion, but shouldn't..really..). And easier on my back. Much easier to sit down and turn a switch on than connect peripheral equipment and strap on the squeezebox.

And Donny is right..we are aging and much of our audience is as well or further. We all love to play what we like, but not everyone is going to continue to want to listen to it. None of us want to be that guy we've seen whose privately loved music doesn't work in public anymore. All you can do is ride the wave until its gone, and be wise enough to know when that is..
