Need another cloud storage service? Google Drive is Google’s attempt at a Dropbox killer, with 5GB free storage, Google Docs integration and lower upgrade prices than Dropbox. At Digixav, however, we wholeheartedly recommend SkyDrive for your cloud needs, as it trumps its rivals with 7GB free (25GB if you had an account before Sunday), great apps on iOS and Windows Phone, and even lower upgrade costs after yesterday’s relaunch.
