Oh, he did not move a different piece but his statement about not taking his hand off the piece is the issue.
But enough of him.
Yes, having most of the e-boards, there are definitely growing pains. The new Chessnut "Beta" app (Android only and on the Evo) is not good. Thankfully we have the Chessconnect extension to play games with the boards. The "surprise membership fees" is for the board (I think) that I consider the worst of the bunch. To tack on that membership thing is just a joke. And I have 2 of them.
Site compatibility is really just here are chess[]com, Lichess has no real compatibility issues.
I am guessing (hoping?) that Chessup learned from the first one about bringing things to market and those lessons are being applied to this project. But it is Kickstarter (not sure why since they partnered with chess[]com) and that is always the risk.
Oh, OK @Rsava, sorry, I didn't see him take it back and move a different piece.
But, no, I didn't back it. Almost did though because I like it. But I've watched these newer electronic boards come to market and haven't seen any without some growing pains. Whether delays, bugs, connection issues, site compatibility, surprise membership fees, limited functionality, or apps for certain OSs ... I guess I'll just wait and see how it develops. I really like how this particular board works though.
