It's okay to be irrational. I am anti-Mac and I have absolutely no good reason. I don't care if anyone else wants to push Mac but I certainly don't. Although I have been not so secretly lusting over the Maclaren Starck. In the right color combination the triumph has been looking better then usual these days too.
Also have to repeat a PP the cybex onyx weighs less then the topaz. Google tells me its 15.2 lbs.
