Just how much bigger is it than the previous Nano? Oodles.

The 6th Generation Nano came in at 1.48 x 1.68 x 0.35 inches, and weighed 0.74 ounces.

The new 7th Generation is just over twice as tall, while also a little thinner and more narrow at 3.01 x 1.56 x 0.21 inches.

At 1.1 ounces, the newest Nano only gained an extra third of an ounce.

Reverting to the tall design utilized in previous generations makes the iPod easier to grip, and thereby easier to use. The designers threw the 6th Generation's clip out the window, so the new Nano is that much thinner.

Switching to the Lightning connector might have saved a little space in the iPhone 5, but its impact on the iPod Nano is pretty profound.
