Multiple MacDailyNews readers who pre-ordered iPads on or near the pre-order launch day (March 12) are now reporting that Apple has notified them that their units are shipping from Shenzhen, China via UPS.
Looks like Apple will hit April 3 delivery dates, for the earliest pre-orders at the very least, with no problem.
[Thanks to MacDailyNews Readers too numerous to mention individually for the heads up.]
