OS X - iOS 8 Handoff
I have been playing with the new Handoff feature in OS X and iOS 8.1 for a while now. Today I had one of those magical experiences. I needed to respond to an email, but was in the car heading to work. I started the response on my iPhone but dictating the message. I arrive to work, but was not ready to send it yet. I walked into my office, opened my iPad, and used Handoff to open the email there. I picked up in the same place .. I just continued typing were I left off. Yes, I could have saved the draft, and opened it on my iPad or my Mac .. but this is so seamless .. it just works!
