On Friday the iPad 2 goes on sale, for the same price as the old one (from $500 for the Wi-Fi-only model with 16 gigabytes of storage, to $830 with 64 gigabytes and both Wi-Fi and cellular Internet connections). And if you thought there was an intellectual/emotional disconnect before, wait till you see this thing.

On paper, Apple didn't do much. It just made the iPad one-third thinner, 15 percent lighter and twice as fast. There are no new features except two cameras and a gyroscope. I mean, yawn, right?

And then you start playing with it.

My friends, I'm telling you: just that much improvement in thinness, weight and speed transforms the experience. We're not talking about a laptop or a TV, where you don't notice its thickness while in use. This is a tablet. You are almost always holding it. Thin and light are unbelievably important for comfort and the overall delight. So are rounded edges, which the first iPad didn't have.
