The big reveal from Apple in terms of the iPod lineup was done Wednesday, and CEO Steve Jobs called this the “biggest change in the iPod lineup ever,” according to a post by PC World’s Ian Paul.

So what is new in iPod-land?

Let’s start with the fourth generation iPod Touch. The new iPod Touch (or as my daughter loves to call it, the i-Touch) has several features in common with the recently-released iPhone 4: front facing camera for FaceTime, a back-camera and 720p high-def video. It also uses the same A4 processor as the iPhone 4. Its resolution is 960 x 640 px, compared to the third generation iPod’s 480 x 320 px. Having the A4 processor rates the new iPod Touch’s processor speed at 1 GHz, while its predecessor’s processor speed was 600 MHz.

The new iPod Nano shrunk – and lost the back-camera introduced with its predecessor – but it now comes with another first: a multitouch screen, with 240 x 240 px resolution. Its screen is smaller at a diagonal distance of 1.54 inches versus 2.2 inches from the previous model, although it now comes at 220-pps density versus the old 204 ppi.

The iPod Shuffle was also given a new look – although this one will be more familiar, with the return of the playback button that was removed in the previous generation. The height of the device has changed from 1.8 inches to 1.14 in the fourth generation, although the new iPod shuffle is a little bit heavier that its predecessor. Battery life has also increased to 15 hours, from ten hours in the previous generation.
