Devotion to OmniFocus Features

The speaker finds it difficult to switch from using OmniFocus because it offers features like automations for organizing tasks, including tagging items from various sources, setting geo-location reminders for specific tasks, having a review mechanism, and allowing links not only to tasks but also to projects and contexts. These features have made the speaker so accustomed to OmniFocus that they feel ruined for using any other task management tool.
