The folks at Smarthome, Inc are out beating the drums for their Insteon automation system, and James Coates of the Chicago Tribune has his reaction. As he says, the larger command space is nice, but it's really the promise of greater reliability that could make it catch on. I've never thought of describing X10's problem as being one of "limited range" but I think James' use of that phrase as a summation is probably good enough for most people. The reality is a bit more complex, but not enough to matter, especially when discussing what makes Insteon attractive by contrast.
