How Is This Different from a Laptop?

I'm on record as saying that the laptop's days are numbered; that the "pad" computer will replace the ubiquitous lapper. (Not soon, obviously, but eventually.)

And maybe not as soon as anybody thinks given this iPad ad. It's for a device that does three things: provides a keyboard for the iPad; holds the iPad upright for typing; provides a protective cover for the iPad. Hey -- how is that different from a laptop?!

Okay -- I get how the iPad is different. I just found it amusing that folks are buying iPads and also devices that turn their iPads back into the laptop they used to use.
