The Next 5 Apple Gadgets To Waste Your Time Obsessing About

Everyone thought Apple would overhaul the iPod touch -- the future of the iPod business -- last year, by adding a camera to it. Nope! Instead, Apple put a camcorder in the iPod nano and left the iPod touch pretty much alone.

So this year, it seems likely that Apple will actually make significant hardware changes to the iPod touch. Like what?

- It could add the dual-camera system that the new iPhone 4 has, allowing iPod touch users to make FaceTime calls with iPhone 4 users, achieving an end-around on the wireless carriers. (Or it might just add the front camera. Or the back camera.)

- It could add the hi-res "retina display" that the new iPhone 4 has, and maybe some of its design cues, like the metal band and (faulty?) antenna design.

- It could add the Apple A4 chip and additional memory and battery that the iPhone 4 has, supporting longer battery life.

- It could make a smaller "iPod touch nano" with a hi-res display to replace the iPod nano.
