Google has made a pair of significant tweaks to its online services. Gmail, notably, now allows users to attach up to 10GB to an email via Google Drive, versus the 25MB the service normally allows. This has some limitations however; people must, for instance, opt into the new Compose function, and recipients with dedicated email clients won't automatically have access to a locally-stored file. In effect Gmail is simply generating links to Google Drive, though this does ensure that recipients have the latest version of an item.
