Apple, 802 .21, WiMAX

Apple would be smart to be promiscuous about radio technologies, if they are in such demand from carriers that they can get away with it. A design that kept the network stack well formed and allowed pluggins in different MAC and PHY in both H/W and S/W would allow such arms-dealer type of approach to design. 802.21 is also designed that way, to provide a media independent upper interface within the mobile device.

As far as WiMAX, 2009 is pretty much a make or break year for it. Let's see what happens. If it gets deployed in places to bring wireless internet (without a voice infrastructure) it might not create such intense competition against the incumbents. Let's see.
