Re: iTV: What you need to know
Forgive my ignorance on this topic, but is the 802.11n specification backward compatible with 802.11g? If so, then I agree it would make sense to use this, or at least, to use whatever the new wireless spec coming along is that's backward compatible with the G spec.
If iTV ends up requiring 802.11n, or whatever it ends up being, it will immediately doom it to failure. Considering no Macs currently ship with anything faster than 802.11g, and, AFAIK, no PCs either, who's going to be able to use it? A pretty limited audience I would guess. I don't think Apple would do something so dumb. They want everyone to be able to use this, Macs and PCs alike, so they have to use a prevalent standard, not some brand new tech that almost no-one has.
Getting past the bandwidth issues using 802.11g is a whole different ball of wax, but I'd guess Apple has a game plan- one that doesn't involve immediately shutting off nearly every computer with wireless capability in existence.
