It depends on the execution. But the idea is simple and I had a use for it just a few days ago - I was going to attend a gathering. I have not noted down the address and can't remember if the invite came through from Facebook, any one of my email addresses, IM or text. If I can go to a single textbox, type the name of the host and popup the invite/address, it would have been great.
