Usually, each generation should be an upgrade to the last. This couldn't be more wrong with the iPod nano. It used to play music only. Then, it played music and video. Then, it got video recording and editing (I think it might have gotten this before iPhone or iPod touch did). Then it couldn't even play video, but can be worn like a wristwatch. Now it can play video again, but can't record video and it's no longer an ideal form factor to wear on the wrist. I would have prefered if it evolved into something like the previous generation, worn on the wrist, but with Bluetooth and the ability to act as an iPhone companion device. Text messages, alerts, music control, music info, caller ID, ...all without removing my phone from my pocket. With the current generation, it's not heading in that direction.
