If you look in the "similar Threads" section at the bottom of this page you will see that pretty much every launch has been considered the worst launch ever by someone.
Personally, I get a kick out of the "if I can't get it launch day I don't want it at all" crowd. That one boggles my mind. I get that people are excited for launch day (hell, I always am) but really? There is only a 24 hour window where this product is appealing to you? Wow. I try to preorder every year and I've been screwed by the website/ servers/ internet connection before. It sucks. But I'll still take the next available delivery date. I want the new iPhone. I don't have to be the first guy with the new iPhone. Different strokes I guess.
