Amazon.com's DRM-free MP3 store pre-loaded on each Android phone.

iTunes is a locked-down service that will only let you play your songs on Apple devices. Quite the contrary, Amazon's DRM-free store will let you download songs online or now, on the G1, and let you take that song to any other device you wish. Want to add it to your iTunes library? Go for it. Want to put it on your Zune? What are you waiting for?

Sure, we've known about this for quite some time--the store already has 6 million songs, you know--but there is a huge base of people who have used iTunes for so long that they don't even know what's out there. Some may not want to switch and will continue using iTunes, but now that Amazon's store is slowly gaining some of the limelight, Apple should start paying more attention to Amazon's offering.

It may only be 10 cents, but saving that much actually matters to people. And when you can buy a song and bring it with you wherever you'd like, it only makes sense that you'd want to buy an Amazon song instead of the same track from iTunes.

Granted, the G1 probably won't sell nearly as well as the iPhone 3G, but we can't forget that the G1 is just one device of many that Google and its partners will be rolling out over the next year. And that's when the real competition will start.
