Initial Orders for New Apple TV Being Prepared for Shipment [Updated: Shipped]
Despite many customers reporting late last week that their credit cards had been charged, some questions about possible availability delays arose after some early customers who had opted for expedited shipping were notified by Apple that the shipping charges were being refunded due to difficulties meeting the company's delivery commitments.
Update: Customers are now reporting that their orders are now showing as having shipped. Preliminary reports indicate that the shipments are coming from Shenzhen, China via FedEx, at least for North American customers.
