I do. I stopped feeling guilty about being successful long ago. I worked hard, and was rewarded, and I am going to fully enjoy the fruits of my labor, as are many people here. Also, the fact that apple KNEW they weren't going to be able to meet demand on some models IS worth complaining over. No company I ever heard of in 2015 has software that can't pretty accurately predict the orders made and stock available. The fact is that Apple knew they weren't going to meet the demand on some models, even if ordered within the first 5 minutes, and so they made it seems like EVERYONE might get theirs later with the "delivery window" tactic.
In 2015 if your computers can't pretty closely predict the orders and the amount you will be able to manufacture, then you are using software from 1995.
