Say what you want about the stupid, impossible-to-control previous generation iPod Nano, but don’t say its clip wasn’t useful.
If you wanted to clip your tie to your shirt whilst making both of them sag thanks to the extra weight, or if you wanted to go jogging and have the heavy little block of aluminum and glass pull at and eventually drop off your t-shirt sleeve, then the old Nano was ideal.
The new one gets handy buttons and no longer looks like a Shuffle-with-a-screen, but it lacks the clip. Luckily, for $20 you can put it right back.
