Extremely useful for running an "Inbox Zero" approach, where all emails can be handled -- either by replying or by denoting a time for showing them again.
I would wish though for a "fixed time" option. Gmails solution ("7 AM tomorrow", "7 AM on saturday", "7 AM on monday next week") for me are usually more suitable than "in one day", since I prefer getting all the rescheduled emails back at once rather than trickling in throughout the day.
