I should be clear that I do not accuse or suspect Tethertools of copying my idea. I think this is most likely a clear case of form following function and the Tethertools table is born out of an existing product line.
I have been giving serious thought to updating my tabletop to not look like a hardware store hack and selling it on a limited basis. As a result I am interested to see this product on the market. Not much more to say about this — but I do welcome feedback if anyone is interested.
