Think about how many times you have lost a document or email, on your own monitor! Super embarrasing. It's OK, happens to everyone. Now, multiply that over your entire organization, per person, per day. You can see, the ROI is huge. If you haven't yet implemented E2.0 or are looking into SharePoint or ECM, make sure this is part of your plan.
Personal Note:
1) I used to charge people thousands for this advice. Comical now, but they paid for the time it took to show them how this could work. Oh the good old days.
2) I've tested this with all flavors of Windows, OSX, and Ubuntu, and all are supported. Go nuts.
