Picking out an MP3 player can be tricky. You can't go wrong with the iPod, thanks to all its travel add-ons. Creative's Zen Vision:M has an amazing screen. And we love the feature-filled Toshiba Gigabeat S. But here's why the Cowon A2 wins: Its screen is as good as the Zen Vision:M's, it packs tons of features, and it trumps those other players with line-in recording. It's the perfect tool for bootlegging your favorite summer concerts (with permission from the sound guy).
