"I'm just not that impressed with Apple finally cribbing off the jailbreak community, and I sincerely hope that the future of iOS is not endless tweaking held up as some paramount of interaction design."

I see the jailbreak tweaks as the alpha version of features that will one day make it into the main source. People who are not afraid to test things out play with and refine the tweaks until they're ready to be official.

I love the fact that at least eight tweaks have been integrated into the main source!
