Didn't Steve flip through 3 iPhones and hardcode the network UI to look like they had good signal?

One of the demos was printing a thing out, but the processor was hopelessly too slow to perform the actual print job. So they hand unrolled all the code to get it down from something like a 30 minute print job to a 30 second print job.

I think at this point it should be expected that every publicly facing demo (and most internal ones) are staged.
