Obviously that feedback is not related to the serial board, as it happens in some iOs without the serial board installed. Comments from this guy are motivated by self-interest. He's made several pitiful attempts in the background to kill the board project from the very beginning, and has been a source of great amusement to all involved in the project. His annoyance with the dual serial project is somewhat understandable, since he can't compete with a board that offers a better product at 1/3 the cost of his offering. We did the serial board as a service to the iO community (and for fun), and don't feel too badly if the profiteers can't compete...especially when the board project with artwork was offered to him early on for free, but he wasn't smart enough to take it. I'm not trying to slam him, as he doesn't seem to need my help for that ;)
I'll take this opportunity to say that this project has been great, with excellent reception by the iO community. The feedback has been 99.99999% positive, with only 1 dissenter (guess who?) who hasn't even seen the board he comments so freely about. Cudos also go out to Jack, who's low pricing for his cable pak and willingness to support sales has allowed this thing to come together. Thanks to everyone.
