I agree with everyone who says that Apple will be phasing out both the iPod Classic and the iPod Shuffle (perhaps the Nano will be renamed iPod Shuffle).
However, the iPod Touch is a part of Apple's future plans, an iOS device that supports the capabilities of the iPhone, but is not an iPhone.
Yes, I believe that Apple will position the iPod Touch as the iPhone killer. Apple will do this by combining their own Skype like app with 802.22.
I know 802.22 (http://en.wikipedia.org/wiki/IEEE_802.22) is down the road, but what if Apple was to add it to a future iPod (or iPad).
802.22 has a range of 62 miles, from one single base station. Now, where would Apple put these base stations? How about in every Apple store for starters. Both NYC and San Francisco each have five Apple stores. If Apple places 802.22 base stations in each store, they would cover both cities multiple times.
Will this solution replace the need for iPhones for everyone, no. But in major cities it would.
Perhaps this is a part of the big plan for Apple's new data center.
So don't rule out the iPad Touch just yet.
This is brilliant.
Apple WILL eventually do this, I believe. A new "Blue Box".
