Madness, and people wait over night for these things
Yeah, I like my iPad, but I don't cream my shorts at every Apple announcement.
In fact, I just bought my first Apple product (iPad II)
in June, which was quite some time after its release. I researched it, compared its features to other models, and spoke with several people who own one. I would never pre-order anything, or rush out to buy a new release simply because it's new.
Had I hurried and bought the latest iPhone 5, I'd have been pissed.
