On paper, the iPhone's iPod doesn't offer any features not already on a fifth-generation iPod: podcasts, videos, music, and playlists are all here, and content management with iTunes is identical. The difference rests entirely in the iPhone's interface. We've used other MP3 players that use touch interfaces, such as the Archos 704, iRiver Clixand Cowon D2, but the iPhone's unique integration of multitouch technology and a graphic user interface put it in a category all its own.
From an iPod perspective, Apple's biggest triumph with the iPhone is the fact that it has returned album artwork back into the music experience in a way that goes beyond a token thumbnail graphic. Physically flipping through your music collection in the iPhone's Cover Flow mode really brings back the visceral feel of digging through a CD or record bin. It's a tough feeling to quantify, but the real music lovers out there will appreciate how well the iPhone reconnects their digital music to a form that is both visually and physically more vivid. Even iTunes users who may already be jaded about using the Cover Flow mode on their personal computer will be surprised at how the experience is changed by using the iPhone's intuitive touch screen.
Truth be told, there is one feature that is new to the iPhone's iPod--the integrated speaker. While the iPhone's speaker sounds thin and is prone to distortion, it works in a pinch for sharing a song with a friend. Apple was also smart enough to manage its speaker volume independent of the headphone volume, so if you're listening to the speaker full-blast and then decide to plug in your headphones, you won't be deafened.
The bad news is that the iPhone's iPod leaves out the ability to manually manage the transfer of music and video content. Unlike any previous iPod, the iPhone does not allow an option for manually dragging and dropping content from an iTunes library directly to the iPhone device icon. Instead, the iPhone strictly uses defined library syncing options for collecting and syncing content from your iTunes library to the device. This should work out fine for most people, but for a device with limited memory the inability to manually manage content seems like a misstep. Our 8GB iPhone was already a quarter full after only a few hours of testing, giving us the impression that users will need to be vigilant at grooming their iPhone library. An external memory card slot is another one of those "nice to have" features.
The iPhone's music sound quality seems right in line with our experience using the 5G iPod. All the same EQ presets are available, only now they are found on the iPhone's main Settings tab. The included iPhone earbuds did a passable job for casual listening in a quiet environment. Unfortunately, the iPhone's recessed headphone jack prevented us from using many of the test headphones we're familiar with. We were just barely able to squeeze the plug of our Etymotic ER6i earphones into the jack to do the comparison.
Watching video on the iPhone is not quite as luxurious as a Creative Zen Vision: Wor Archos 504, but its wide screen and bright contrast beat the fifth-generation iPod by a mile. As with previous iPods, video playback is automatically bookmarked so that playback resumes where you left off. And because the iPhone is a phone, it includes an airplane mode that will keep the music player activated while turning off the call transmitter. Thanks to the January 2008 update, you can also browse movies by chapter as well as view subtitles. Other changes include the lyric overlays on music tracks, support for the new iTunes movie rentals, and the ability to redeem iPhone gift cards from the device using the wireless iTunes store.
