T-Mobile G1 vs iPhone 3G: Can Google bite Apple?

The G1's music player isn't as easy to use as the iPhone's and doesn't come with any fancy graphics. We're also bitterly disappointed there's no built-in 3.5mm headphone jack (right). The G1 doesn't lock you into iTunes, however, and you can simply drag and drop music files into it, which is something we wish the iPhone supported.
