And what way are you NOT part of the problem? Why did you selfishly buy two iPad cases when you were not planning to use them? Well, to me the answer is pretty clear, as you admit here -- to sell on eBay.
I bought my WiFi iPad on Launch Day and bought an Apple iPad case to use with it. On this past Friday I bought my 3G iPad and, yes, there were some Apple iPad cases on offer then, too. Did I buy one or two or three? NO. I figured I have the one already and also have other ways to protect and carry the second iPad so left the iPad cases available for those in line behind me who were getting their first iPad and who needed and wanted that case. If I decide that I want a second Apple case for my own use, I can wait and buy it in a few weeks when the initial demand has tapered off.
It is greedy people who have caused the need for setting limits..... I applaud Apple for the way they have approached this situation.
