With the iPad Air now having launched in over 40 countries today, supplies of the device are starting to weaken in some of Apple's online and retail stores. The most significant signs of tightening supplies are appearing in higher-capacity models in some countries, specifically 128 GB and 64 GB cellular models and 128 Wi-Fi models. In a number of countries these models are now listed as shipping in 5-10 business days. Apple's U.S. online store continues to list delivery dates of November 4 for new orders of all models, while those looking to use Personal Pickup to order their devices online and pick them up today at a nearby U.S. Apple retail store will find that supplies are beginning to dry up with increasing combinations of models and stores now listed as "Ships to store" rather than "Available today".
