Apple iPod

The 8GB/16GB version of the iPod Touch is now less than $300, and the 32GB is $399. The glad thing is iPod Touch is thinner than its predecessor and includes a built-in speaker and a volume switch.

Now, we also got iPod Nano ??? Can anyone tell me what is the difference between iPod Touch and iPod Nano? Which is the better choice? Pls tell me.
