Reverse engineering confirms Apple iPad is 'a really big iPod Touch'
The pictures and details are juicy -- you can even order a bunch of die photos! -- but ultimately, there isn't anything exciting under the hood. The iPad is merely a large iPod Touch, with almost identical hardware in places. Chipworks calls the iPad 'a giant battery with a tiny [circuit] board attached to it' -- and looking at the picture above, you can see why!
So, no real news here I'm afraid, unless you're trying to mollify a Mac fanatic. What you're paying for is a large touch-screen and a giant battery -- you are not buying a piece of 'magic', but simply a large iPod Touch. The devil, as always, is in the software. It would not be the first time that Apple has shoehorned some fantastic software into a shiny, but otherwise lackluster hardware package.
In my opinion, the coolest part of this story is that Chipworks tears apart of bleeding-edge technology to produce full, reproducible schematics of a device's circuitry. Nothing is sacred!
