I've been checking the Apple Store website with increasing frequency the past few days to see when my new iPad was scheduled to shipp, expecting it to arrive sometime today as promised. But when I saw this morning that my order had not left the warehouse, and that my credit card had not yet been charged, I called Apple's customer service to find out what was up. The first woman I spoke to assured me I could expect delivery sometime today, even while acknowledging the iPad hadn't left the warehouse. The second time I called I was told the device would ship by May 7, even though my pre-order had been placed such that I could expect an April 30 delivery.
So I decided to trek up to the Apple Store to see if I could straighten things out and get my hands on a new iPad today. The plan was to cancel the online order and replace in with a retail purchase in the store. The staff was very helpful and put me on the phone (an iPhone, of course!) with Apple's customer service to work things out. But I waited on hold for over 25 minutes without connecting to a human being and the Apple Store manager was so embarrassed about the hassle he bought me free Apple case for the iPad ($40 value, so this was a VERY nice gesture!) and also allowed me to use a $100 gift card I had for part of my iPad purchase (which normally they can't do in the Store).
Anyway I am now in possession of a new iPad with WiFi + 3G in the 32-gigabyte flavor. It's awfully nice.
