Years ago I used to work for a company that built high end Kit Cars (Quantum Sports Cars - google them). These cars were built better than TVR, they were fast, strong, comfortable, safe and the convertible was sooo much fun!. However they only ever attracted 'alternative' buyers. In the end the company folded.

The main problem with a keyboard running an OS such as Linux or Windows (the latter should never be used for live music in my oppinion) is the customers perception based on ignorance, just like the cars we were building in the 90s.

Another company that used Linux is DLQ who make the most authentic clone of a vintage Hammond I have ever played. However it took a while to boot up, and it was not taken seriously by the competition who would make false claims regarding reliability - using peoples ignorance of linux based PC against the KeyB.

Now they have moved to a dedicated computer its a completely different story. And the KeyB is now a serious contender and selling incredibly well.

I don't think any PC based system running plug-ins will ever be as succesfull simply due to lack of understanding.

Educating the buying public is not an easy task!
