I am still in the middle of uploading my 26GB music library to the cloud, but I have a few comments on the whole thing:
-From what I've seen, it looks to be a promising service. I can't wait to see where this will go in the future.
-I am disappointed that there is nothing between the 20GB and 50GB plans. Such as 30GB, or 35GB. I have a little over 20GB, and am forced to go with the 50GB plan - which I will NEVER fill up.
- Since I have SO much available space, I would LOVE it if I could upload movies to the cloud!
-I also have not tried it yet, but when you buy music from the Amazon store on your phone you are given the option of saving it to your phone, or to the cloud. I wish I could do both (even if it does take up space on the cloud, since I have so much available space, I don't really mind). I like having my music on my HDD and in iTunes (I will still use iTunes for my computer - this service is simply for getting music to my phone, without taking up SD Card storage)
I was under the impression if you buy the music from amazon and choose to download it to your phone it is also stored in the cloud it just does not go against your storage.
From the OP "...new purchases from the Amazon MP3 Store are stored for free and do not count against your storage quota..." You have the option to not download the file at all if you do not want native access to the file and just want it in the cloud.
