The new Touch has a visible speaker grill on the bottom (to the left of the dock connector). On previous iPod Touches, the external audio simply came out the dock connector. Apple likely beefed up the speakerphone to enable FaceTime on the Touch.

The new Touch has once again been slimmed-down. Similar to the iPhone 4, the back of the Touch is now flat. Unlike the iPhone 4, the iPod Touch still features the same shiny stainless steel back that has graced every iPod Touch.

We paid $229 for our 8 GB Touch, which seems like a pretty good deal. A 32 GB Touch will set you back $299, and a 64 GB can be had for $399.

Bogus math: In dollars per gigabyte, the 8 GB Touch is a terrible deal: $28.63/GB. With the 64 GB Touch a gigabyte will only cost you $6.23.

Want bogus logic to go with our bogus math? BusinessWeek has a fallacious column up on how the iPod Touch costs $29 more than the iPhone 4.
