I use Siri on my iPhone to set reminders and funnel them into Remember the Milk. When you setup Siri you can tell it what email address to use for email reminders. I put in the remember the milk unique email address for sending reminders. This way I can say "Remind me to pick up milk" and it will email me the reminder which will automatically show up in my Inbox list for further categorization. Great time saver and with me whereever I go.
