I paid cash for my iPad2, never really thought of the scalpers. But if you really think about what you're asking, does it make any sense? When did fairness take over common capitalism? Not only on the scalpers side but on apple's side as well.
If you were making something that everyone wanted, why would you restrict who can get it, let alone how many. I can understand the "how many" aspect so that it makes it difficult for scalpers to just have one person in line by a truck load, but it also makes the scalpers lives a little more difficult in the sense that they have to get more people to stand in line to reach their quota. It's a bold move but if they want it, they'll get it.
Same goes for apple, why would they stop selling a hot item? cause its not fair to the general public that wants it? I understand that, but in the business world where my money matters, no one will give you a chance. It's pretty cut-throat when it comes to money. When it really comes down to it, sure apple will lose money to scalpers, but gain it back from the app store (possibly).
My advice, don't stress too much about the scalpers, order it online and forget about it till it shows up, otherwise you'll just get more irritated at the fact that nothing can be done, nor will be done.
