Anyone remember the old days where you needed to check your voice mail, then find the document they wanted on the voice mail, go to the fax machine, load all 97 pages of it in the machine, punch in the number and fax it assuming it didn't jam the paper. These where the good ole productive days.
Now you get the email on smart phone, access cloud storage and in 5 seconds you grab the file and email it back. All this while you are sitting in a meeting.
