To address this issue, we must let our customers know that a new version of TypeMatrix is highly unlikely. We would love to have a bluetooth version, and many of you have made wonderful suggestions about changes that could be made to make the layout better (for you), but truthfully, to make any changes at all would cost us at least $100,000, and we are a VERY small company without that kind of capital. We have tried, over the years, to find a larger partner who would recognize the brilliance of the TMx design and help us to produce many different models, one of which would fit almost anyone. But that hasn't happened. We are happy to be able to produce this quality product, support the customers who appreciate the changes we have made, and just keep stocked with products that people want. And we thank you for your support in doing this!
