None of this is to say that you shouldn’t buy the iPod touch. In fact, based on my early testing, I’d have to say that the iPod touch is by far the most amazing product to ever bear the “iPod” brand name. But be forewarned that the iPod touch is not necessarily the mythical “iPhone without a phone” that some users have been looking for.
It’s much closer to being an iPod plus Safari, Multi-touch, and the store.
You can double-click the Home button to bring up on-screen playback controls, even when the screen is locked. Nifty. But, unlike the iPhone, the Touch has no hardware volume buttons, and it doesn’t have a play/pause/next-track clicker on the headphone cable. That clicker is my very favorite thing about the iPhone’s music player; I think it’ll be a pain to use an iPod Touch that’s in your pocket.
Of course the iPhone has great software, but the hardware—the screen, buttons, clicker, earbuds, and durability—are what have really impressed me.
