That's no reason to include Wifi. By that logic MacBooks should all have the same features as the Pros because all the R&D and parts suppliers are in place. But they don't have backlit keyboards, FW800, or dedicated graphics, partly due to price points, mostly due to keeping the lines distinct.
What you just said contradicts what I said above. Your logic assumes the prices are different, which I've listed above as a 100GB 6th gen. iPod (with Wi-Fi and all) being the same price as the iPhone. What I meant was that the R&D was done, all the work for getting the parts was done, etc. There's no real work involved, all they have to do is take the iPhone and
remove things from it.
Maybe only the high-end model of iPod could include the Wi-Fi and programs part, but as I said above, the competition isn't standing still either. Adding the software doesn't add anything to the cost of the iPod, and Wi-Fi ICs can't cost that much if they can fit them inside 20$ Wi-Fi Network Finder keychains.
Now that we've seen what Apple can fit inside a case the side of an iPod, we want those features. And a 8GB iPhone is useless for someone who needs, say, 60GB of storage space.
Edit: I really don't understand why so many of you think that Apple should not include the Wi-Fi, Safari, Mail, Google Maps and all on the next iPod. Saying "but it's not what an iPod is for" is a weak argument. Imagine saying that about videos when the 1st or 2nd gen. iPod came out. You would have been the ones saying "but the iPod is for music, movies have nothing to do with an iPod." It's the progression of the iPod, and now that Apple has shown it for the iPhone, we know it exists, we know it can be done and we want it for the next iPod too. It's as simple as that.
Why would the high-end iPod be tied to a phone carrier, it makes absolutely no sense. And that high-end iPod is limited to 8GB of storage, which makes it a pretty weak iPod IMHO. That's like being forced to get dial-up AOL internet access with your Mac Pro. Oh, and that Mac Pro only has 40GB of drive space too, by the way.
