Att website pre-orders

So was this a good Idea, how much of a delay will I have, should I have waited in line with all the JO Macers.

Pre-orders for iPhone 3G S will be shipped with overnight priority and will be processed to arrive as early as June 19, 2009, if submitted by 12 p.m. noon C.T., June 17, 2009. The actual shipment date and receipt of your order is not guaranteed and may be subject to delays for reasons that include, but are not limited to, product availability, inventory, credit issues, number porting or carrier delays, and completion of other required AT&T business processes. Additional items added to the cart at the time of your pre-order may ship separately depending on availability. Your credit card will not be charged until items are shipped. All pre-orders taken online are being handled on a first-come, first-served basis.
