If you want a Smart Keyboard and Apple Pencil for the iPad Pro, you’ll be waiting awhile. They’re now showing a 4-5 week waiting time for availability.
What’s more, Apple has sold out of most 128GB models (both the Wi-Fi and cellular versions). Availability of specific super-sized iPads at specific retail stores varies from location to location, some have the 32GB model in stock, though the both the Wi-Fi and LTE 128 gigabyte variants are harder to find.
Regarding the situation Apple told Mashable this: “Customers are very excited for iPad Pro, Apple Pencil and the Smart Keyboard. We have limited supply of Apple Pencil and the Smart Keyboard in Apple Retail stores. Our stores will continue to receive regular shipments and we encourage customers to visit Apple.com for online availability and delivery dates.”
