I ordered the exact same computer on Tuesday morning. (Yes, I broke down and ordered the RAM from Apple. I've always gotten it from third party resellers but Apple's price reduction was just enough to appeal to my lazier, instant gratification seeking side!)
So, I ordered Tuesday morning, it was prepared for shipment Wednesday morning, and today it went from San Jose to Sacramento, and then departed Sacramento. The interesting thing is that when it first left San Jose, "expected delivery" was May 14th. That sounded about right for FedEx ground from CA to CT. But when it left Sacramento, "expected delivery" changed to May 10th! That's just 48 hours from Sacramento to my door in CT!! Is that even possible? There is also a note to the effect that the next tracking update won't be until May 10th, which is the same day as expected delivery. Is it possible my new iMac is a stowaway on an airplane? And May 10th is a Saturday...
