Yeah! It is so obvious that Apple explored many potentials before arriving at the announced iPad. People are just SO stupid not to figure it out, even from a company that - as Jobs put it - get rid of the unNecessary stuff ( which now wisely they patent ). When i saw the Microsoft surface keyboard i though Apple did that already, it is so obvious. The end design is always a result of various failures, and hardly the 3rd or 4th take.
