It would be great to open a document on one device, such as my Android (or iOS, for others) device or PC, then be able to push it to another device and have it open and ready to use immediately. This would be great when moving between meetings or locations.

For instance, when I am out to lunch and receive an email with an attached document, I might open the document to look at it a bit, but would like to focus on it more when I get back to the office. If I could hit a "push to device" button to make that document open on my PC back in the office (or just push it to all devices I am logged into), I would see it front and center as soon as I get back.

The same could work in reverse. If I am editing a document before a meeting (or a class I teach) I could be editing on the PC, then when it is time to go to the appointment, press "push to Android" to have it open on my phone or tablet and ready to use as soon as I unlock the device.

This saves time versus finding the email that had the attachment, or saving the document to a folder, renaming it, then looking it up again when I get to the next location.
