Amazon may have just changed that.

Now, Amazon's Cloud Drive is only part of the picture. First of all, keep in mind that Amazon's Android app -- officially called Amazon MP3 -- comes preinstalled on plenty of Android phones. That means those devices are now fully equipped with the new Cloud Drive and Cloud Player services right out of the gate. All the user has to do is sign in once.

Next, factor in . Launched last week, the store strives to serve as an alternative to the main Google Android Market, using exclusive offerings, daily freebies, and friction-free Amazon checkout to attract customers. While the reach of Amazon's Android app store is still relatively small, it likely won't take long to evolve. Already, we're seeing the launch of the first U.S. smartphone with Amazon's app store preinstalled: the upcoming HTC Merge by Cellular South. Odds are, that's just the start; it only makes sense that Amazon is working hard and fast to score broader distribution deals for the future.

If all of that isn't enough, ongoing buzz suggests Amazon may eventually come out with . But I suspect that's the smaller story compared to these software-oriented offerings and their potentially enormous reach.
