Steve Jobs is saying it is easy to copy. But if you're great, you steal the fundamental idea and do something totally new with it.
Apple didn't just copy the phones already on the market, they stole the idea of a cellphone and did something fundamentally different.
So different that we had 6 months of people saying it was going to be a failure, Ballmer going on the record saying there's no way they'd sell any significant numbers, and the RIM engineers telling upper management that the iPhone couldn't possibly work the way apple said!
Thats "stealing" -- doing something for which there is nothing comparable on the market, in Steve Jobs view.
Copying is when you look at a successful product and mimic it down to the millimeter.
