Google Drive is very much like the hugely popular Dropbox, and offers 5GB of free storage. I use Dropbox every day and have also begun using Google Drive. Any files I save to my Dropbox and Google Drive folders are almost immediately available on my other devices. I'm on vacation right now, and it's been such a convenience to have all my working files from my desktop computer available on both my laptop and iPad. I also like the feature that as I edit a file, my changes are immediately uploaded to the cloud. There's no longer any risk of losing my work. Ars Technica has a hands-on review of the Google Drive app. The main issue with using these services on an iOS device is that most of the files you access in the cloud are read-only. Tecca also faults it for not being able to edit any files in-app. But as Ars Technica points out, Google has recently purchased QuickOffice, one of the iOS office suites that works seamlessly with Dropbox, so maybe this functionality will soon be offered in their Google Drive app.
