Personally I think it is great that a manufacturer is making an extremely portable product like this available. You can treat it as a sound module but at least has keys for the times that is all you want to cart it around alone. I have played a CZ101 onstage so the keys arent a problem for me. Personally for the price I think it is a winner and fills a niche that no other manufacturers are filling. I would like one because I can't fit another fullsize keyboard in my car but this I could and MIDI it up to my main keyboard. Anyone comparing it with a cheap fullsize keyboard are simply missing the point of it being so compact and arent the market it is being aimed at.
