I am using Boomerang pretty often. For instance, right now I have an e-mail scheduled for tomorrow. I wrote it to a colleague that was on vacation while I was writing the message (a follow-up on a bug). In some way, I'm helping him manage his Inbox effectively: this e-mail didn't need to be read while on vacation, so why should he care. My other typical use case is when I write an e-mail at 7pm, but I prefer it to reach the recipient the following morning at 8.45am. First, because it's working hours, so the chance that it gets lost is lower, and second, to pretend I wake up sooner than I do :) I don't use the "postpone me receiving this e-mail" feature. For that I prefer calendar. But I do see its value.
