Using electronic task lists to run your day

Like many Aspies I can get drawn off task by the myriad of environmental distractions in an office:  meetings in the aisle behind my cube; someone's cell phone turned up to 'I am at a rock concert and still need to hear my phone' levels; the flickering of those damnable lights. I will easily go to one of my favorite stims/obsessions like hitting the random link on Wikipedia or the random LOL button on I Can Has Cheezburger.

Thankfully Outlook (and other email applications) has a lovely task list that provides reminders and even the capability to schedule reoccurring tasks. I  often use this to keep myself on task at work or remind me that I should be on task.
