When you're holding something the way you hold an iPad -- or at least the way I do -- the weight of the device is amplified through leverage. I tend to grip my iPad the way I do a book; near the bottom. The fulcrum point of support is at my wrist, which is always far from the center of gravity of the iPad. Gripping it from the bottom makes it worse, as the total weight of the iPad is suspended above my wrist. I constantly find myself swapping between gripping where I want to grip (near the bottom) and some other position that requires less effort. Even then, human anatomy dictates that the fulcrum point is always well outside the bounds of the device. I've owned an iPad 1 (680g) and an iPad 3 (650g). Even the seemingly tiny reduction in weight was noticeable when holding the iPad near the bottom. I've held an iPad Mini, and the difference is night and day. The iPad Air weighs 181g less than the iPad 3, but only 138g more than the iPad Mini. That means the iPad Air is closer in weight to the Mini than it is the outgoing iPad. If you don't think that's an appreciable weight difference that you'll feel every time you use an iPad, then you've got some serious gorilla-strength arms.
