Okay, how are we all seeing some moral downfall of Steve Jobs here? I mean... Perhaps we should just see what's shown at such events realistically. I mean, who wouldn't show their product from the best side possible? So they faked some reception. Of course they want younto see the "optimal case", right? Same goes for swapping Devices in case of some failure. When they show their device, they want to show what it will be like, so they will not let you see a ton of bugs that are about to be fixed for the release anyway.

Besides: they cannot deceptively, promise you fake stuff and people will be lead into erroneous decisions by them. Quite the opposite. Think about it: anyone who actually watches those presentations is not your standard customer, right? They'll be invested or knowledgeable anyway. So if they promise you utter bullshit, people will notice your lies immediately. Tests will chide you for it, people will distrust you, sales will go down. So don't assume that any beautification of the product at such presentations will lead poor, uninformed customers to buy the thing. Quite the opposite. They will more likely not hear too much about the presentation until the "they lied!" Cries start.
