Well, I'm not placing an iPad pre-order, but I wouldn't call my friends and colleagues "idiots" if they want to be the first ones who own an Apple iPad.
PC World has a story titled, "iPad Pre-Orders: For Idiots Only." The word "idiot" is a strong word. I think "dummy" would be better, given that the "For Dummies" book series have done really well.
The Apple iPad still remains a mysterious product in that we haven't had a chance to hold one in our hands. However, we know the specs, we've seen the videos, so what more do you need? If you don't live near an Apple Store, you may never get to try the device before you buy it.
