Apple’s stock of AirPort base stations is beginning to sell out, MacRumors reports, following the company’s formal exit from the Wi-FI router business last month. MacRumors notes that the AirPort Extreme is already being listed as “sold out” on Apple’s online store in the U.S., although it remains available in limited quantities in other countries, such as Australia, Canada, Japan, and Singapore. The smaller AirPort Express and storage-equipped AirPort Time Capsule models still remain in stock online in several countries, although the entire AirPort lineup has disappeared entirely from Apple’s online store in several European countries. Apple stated last month that its AirPort products will continue to be sold “while supplies last” although nothing was said about what those supply levels are.
