After jailbreaking, you lose privileges ... you can escape the walled garden, but then you can't have what's in the garden anymore.

You PAY to have a watch battery replaced? I don't. I walk up to a jeweler, and they replace a watch battery, free. Never had any of them charge me labor for doing it. And from the youtube vids I've seen of people doing it themselves, it's not easy, cracking the case, etc. They MADE it deliberately more difficult than it would have to be, for monetary reasons ONLY. Plus you would be voiding your warranty (though that's minor in practical terms, since it'd typically happen long after the warranty ran out).

And yes, the iPhone no longer is so marked up - because it has competition. iPad will likewise be going down in price - because of competition. Doesn't change their willingness to levy an extremely high profit margin on people when they CAN. Again, I'm not saying it's wrong - I'm saying I don't respect it.
