Joining in with iCloud, Dropbox, and others, yesterday brought the announcement of Google Drive. It's a cloud storage solution that, of course, integrates well with existing Google products. Google Drive will offer 5GB of storage for free, with upgrade options for a montly fee.
Google is pushing the ease of use across platforms. Mac,PC, or mobile, items saved in Google Drive will be accessible regardless of platform. At first, it doesn't sound like anything special. I already get my Gmail and Google Docs on several devices, and they're already in the cloud. However, Google Drive will eliminate attachment size caps on emails. Just add the file to Drive, and link to it. No uploads, no zipping, no attaching. There's definitely potential there.
The service is slowly rolling out to users. Visiting their website, you can sign up for alerts on when yours will be available.
