What is the difference between the Zire 31, 71, and 72?

Question

Which one do yall think is better and what is the difference really?

Answer 1

The 31 is a budget one, cheap 'n' fine.
The 71 is a middle of the road performance PDA with a hidden camera. It also is designed for gaming.
The 72 replaces the hidden camera with a movie camera, and removes the game joystick, but adds bluetooth.

You can't buy ANY of these anymore. The 31 has been replaced by the 22. The 22 doesn't have an MP3 player or that much game support, but hey, it's super cheap! If you want a Z72 sans camera, get a Tungsten E2.

Answer 2

Color and memory.

The Zire 72 gives you a lot for your money.
