Sure, well, I use Lotus Notes, because we use that as our enterprise application, and I use the e-productivity add-on to the Lotus Notes that my friend Eric Mack designed, which turbocharges the list management and the e-mail and calendar management within that context in a GTD kind of way. So that's how I manage [my] calendar and my action list and so forth. I'm still syncing to a BlackBerry, because we haven't upgraded our back-end server so we can do these on iPhones; I will do that as soon as we can do that.
