Same Boat.
I ordered the same iPad 2 as you at the same time... and mine is following the same shipping schedule as you... hm...
Would you know if "left the ramp" means got into a cargo area on a plane? I'm a skeptic by now having watched my iPad2 in its pallet at Lantau Island for 4+ days and "Prepared for Shipment" for 3 1/2 days - I'd be really happy if it were finally on a flight.
