A month ago Apple announced at the WWDC in San Francisco that they are "demoting the PC". A couple things are quite notable about this, and maybe not very obvious.
First, they are beginning to use the term "PC" to mean either their traditional computing products or Microsoft-based competitors. If you watch past releases, PC had been a deragatory term. My belief is that they are trying to mainstream their products a little more, since they are now trying to appeal to the non-tech crowd more and more. We've seen Microsoft go after the same market with the Microsoft Stores brand, and HTC is doing it with a female-targeted phone. I don't mean to draw too many inferrences here, I just mean Apple is targeting outside the current tech market.
Second, they make it quite clear they are cutting the cord. This is good, and actually shows Apple's hand a bit- the only thing that is common between all the products at this point are the cables! You only need the cable for syncing movies & TV shows, since they appear to be outside the realm of the current updates. Other than video media, you really only need the cable for charging.
Now think big, for a moment- really big. We've had the same chargers on our laptops, phones, electronics, etc. for a long, long time. We've heard rumors of small iPhones for a long time, and I think this is the direction they are going- two tiers of Apple products:
The Top Tier: This is the flagship product- eventually 4G/LTE, large screen, dual core CPU, high-res camera, and NFC. Pretty much anything you can dream up is going to be in this phone. It will remain similar to what you see today.
Second Tier/Green Tier: This will have a scaled back CPU, a camera similar or identical to the iPhone 4, maybe even the same screen. What will be absent is the larger screen and other bobbles- what it will have to differentiate is a much more efficient design and a solar charger. Adding that with advanced cloud-based syncing probably due in 2012, you would see a phone that never needs to be plugged in.
These are the general directions that the market is going, but I think Apple is poised to get there first. I am still baffled why Samsung is not leading the market, in technology- they have all the bits to do this with Android, but the Apple competitors are just not showing the inspiration or vision at this point.
