Aside from its rounder form, the bottom edge of the Apple iPod Touch is unchanged from the original version. Apple's 30-pin connector sits at the center, while a standard 3.5mm headphone jack sits off on the right.

Competing MP3 players like the Samsung P2 (right) do an admirable job emulating Apple's touch-screen control. But when push comes to shove, it's easy to tell which of the two companies has more experience with software design.
It's a small thing, but the amount of parts enclosing the iPod Touch have shrunk from three pieces on the original model (back, bezel, and glass) to just two pieces on the second-gen (back and glass). Maybe it's psychological, but the two-piece construction of the second-gen Touch feels more durable than the original, in spite of its thinner design.
CoverFlow is fun, but when you want a more exact way of finding a song, you'll need to scroll though a list. Fortunately, Apple provides quick tabs for sorting at the bottom of the screen, and a fast-find alphabet strip on the right side.
