Amazon has a pretty decent cloud service. For 69 cents it can be upgraded from the free 5GB plan to 20GB for 1 year. You just need to buy any album of your choosing. I purchased Dr. Dre - I Need a Doctor, as many of today's top hits have went on sale and are eligible. The problem is, I do not see anything besides the Amazon Player to access the cloud. The Player is great for music, but a native app would be nice to do the following. Play stream-able MP4's. View Photo's Auto Sync Mobile Photo's Open Documents Backup's Install APK's Sync with PC (would need Windows/Mac/Linux software) SugarSync (5GB Free)/Dropbox (2GB Free)already offer many of these features and have native Android applications. But taking advantage of the 20GB would be nice. Note: Moderator's I have removed the referral links. Thanks for the warning.
