Also, I wrote several emails late last night that needed to be sent this morning. I didn't want to log in this morning to send them. Enter Boomerang for Gmail - http://www.boomeranggmail.com/. The service will let you schedule emails for a later time and do two more things I haven't thought through:
1. Boomerang an email back into your inbox at a later time. Think bills, follow up calls, etc.
2. Boomerang an email back to the recipient if they don't respond (or just as a reminder).
Where do you think I got the idea of Inbox Zero? duh. The second power might be too much. Heck, I am not sure I'll use the first, but the ability to delay send? That's gold.
