Well if it makes front derailer shifting as precise as rear derailer shifting, never needs any adjustments or trim, and you are able to shift the front derailer (even cross chain) under full load, that sounds pretty good to me.

The main thing that kills it right now is the pricing, but new products are often released at a very high price point. Right now they are really only going after racers or the very 'well off' enthusiasts. That first review compared the people calling electronic shifting a 'gimmick' to the guys that said "carbon would never last, that aero bars would never catch on, that the internet was a fad." That's a pretty bold claim.
