Imagine you’re in a meeting out of the office and someone calls your desktop and leaves you a message. Wouldn’t it be cool if, on a break, you could just open your laptop or smartphone or tablet, get an email with your voicemail in it and call the person back right from the email?
And how awesome would it be if organize and start a conference call with the members of a project team right from the Word document that has your team members’ phone numbers on it?
