not shipped
I ordered a 63 GB 3G (AT&T) Black at 6:11 AM EST (time stamp of email confirmation) and it's status still sitting there showing that it will be shipped in 3 to 5 days with a delivery date of March 18 to 25th. If it doesn't ship within the next 24 hours, there's no way they'll make that delivery time frame.
On a side note, the cover I ordered "shipped" Sunday (picked up Monday) and has currently been in transit somewhere in Hong Kong for the past day and a half. It had a ship time frame of 1 to 2 business days with a delivery by date of at the latest March 21. I don't think it will make it here by then either.
Apple was in no way ready to ship the iPad 2. They should have simply made March 11th the pre-order date if they weren't planning to ship until the following week.
