We saw how well the PS3 works with Zunes (not at all), but how does it work with iPods? Well, it's recognized, which is better than nothing. The only problem—which is a major problem—is that the PS3 only browses the iPod like a portable hard drive. That is to say, it doesn't sort by artists, albums or playlists. And if you're familiar with the way iPod stores music, you'll know there's no logical structure.
What does this mean? It means the iPod is all but unusable unless you remember which folder your song is under. Bummer.
