Google Drive, 6 years in development, is slowly rolling out to users. I happened to notice my Google Docs app had been replaced on my phone by an app simply named Drive. Alas, my account is not yet ready to access the Drive service but am indeed waiting in anticipation for it to be ready to use.
The major concern here is for existing cloud providers such as Dropbox, and of course Google Drive will also be in direct opposition of Apple’s iCloud. Google are offering 5Gb free to everyone, and buying additional storage is cheap as chips since after all Google have more storage and cloud capacity than anyone else. What will be interesting to see is if Google make a direct attack on iCloud, offering synchronization between mobile, web and desktop for apps, music and photos. No doubt, if Google don’t directly offer this service there will be a plethora of developers happy to open up this area of features as Google Drive has API access for developers to take advantage of. For now, the Google Docs integration is nice.
Google Drive is being rolled out in the usual Google MO, phased release with some seeing availability before others, in the meantime you can download the Google Drive and request a notification to be emailed to you when your Google Drive is ready for use.
