- I have Google Play Music synced with iTunes on my MacBook Pro and have my entire library (nearly 5,000 songs) on the cloud and can listen to it all via wifi with my S3 at work (for example) or from any other device I choose, soon will do it from my Nexus tablet as well when I get it. The streaming works great and you can choose to stream the music in high quality.
- I use Google Drive for online storage of files, backup of important files and for making and sharing folders for clients so that they can upload project related files there.
- Picasa and Google+ instant upload for the pictures I take with my S3 and other images I have on my MacBook Pro.
- As for the rest all my email, contacts, calendars, rss feeds as well as browser history, data and bookmarks are tied to my Google account so I can access them on any device I am able to log in with it.
I personally find it quite liberating to be able to access all this from any device with an internet connection and a browser. Moving everything to the cloud is definitely the future in computing and I couldn't be happier to have done so.
