Gmail Integrates with Google Drive, Allows for Attachments Up to 10GB

Gmail just added a new feature that lets you "attach" files to messages by selecting them from Google Drive, giving you much more leeway in how much you can send.

Drive allows you to send files up to 10GB in size, which is much larger than you can send with traditional attachments. Just click the "Insert files using Drive" button in the Compose box and choose the file you want to send. Of course, if you're a Dropbox user, you can get similar results with desktop clients like Sparrowand Postbox.
