Apple(s AAPL) may have already gone through its initial supply of new iPads available to ship by this Friday, but you can still place an order and get one of the new tablets in two to three weeks, according to current Apple website estimates.
Over the weekend, USA Today noted that iPads scheduled to arrive on customer doorsteps March 16, the first day the new tablets are available to the public, were already "sold out." To be clear, you can still order a new iPad, but you won't receive one from the first batch of shipments.
