Limited availability of Apple's wireless AirPort and Time Capsule base stations suggest a hardware refresh, with new rumors indicating the company will shift its wireless base station line to use iOS.



From Apple Insider:

Apple's existing AirPort and Time Capsule products have for several years used embedded ARM processors built by Marvell (the original models used AMD and later PowerPC chips), but they run a unique embedded operating system.

Shifting these products to use a custom build of Apple's iOS would make it easier for the company to port content streaming, sharing and other networking features between Mac OS X, iOS and its AirPort base stations.
