My $.02 on this.....

I decided not to take on the PSIM as a product due to the RS232 issue. 
It does not make business sense to make a music product that does not 
have USB and Mac compatibility. The Atom Pro is also very expensive.

It does make sense for dedicated hobbyist use.

I suspect someone will eventually put together a Basic solution that 
makes sense in today's market.
