It really comes down to your personal riding style. For a touring rider who may be 100 miles away from the nearest bike shop, a 36 spoke wheel that can stay true enough for use with 4 broken spokes may be way, way, way more important then saving a gram or two, rotating or not. Heck you might want a heavier flat resistant tire on it as well. Another group that would be interested here, is the commuter crowd, popping a spoke on the way to work, and being able to just tie it off and keep going, to fix it when you get home is also important.

Of course if you race, and getting there 4/100ths of a second faster is the most important thing and if your willing to take the risk that a popped spoke will end your race, then then you want the lightest wheels possible. Then again you probably don't want a heavy touring bicycle either At least not on race day, although I would bet (If I were a betting man) that most pro racers have a heavy steel training bike that they ride most of the time, saving the Carbon for race day.

What is refreshing about this, is that someone is actually building rims that are not racing oriented. It's a growing market, and as gas prices head up again (it's the beginning of the summer gouging season ). Expect more people to be interested in touring and commuting by bicycle again.
