I guess I'm the only one that doesn't see the big deal in this?
If you are going on vacation, and such.. like shootergirl, that does suck... I understand the disappointment there.
For the rest of us, everything wasn't supposed to be launched until tomorrow. Maybe it was just a glitch... (it happens a lot) that the page got launched before they had the products in stock.
I placed a big order too, and I got the email. Intially I was disappointed when I saw that it will take two weeks to ship, but obviously that is false. That's kinda a safety net to them... just in case it may take UP TO two weeks. Everyone is calling, and some has been shipped out already, and many people posted everything will be shipped on Friday at the latest. That's not a big deal to me. They gave you the option to cancel your order no problem... so then you can go to your counter to purchase everything.
I don't think the problem is that MAC goofed, it's more like we are all too impatient.
