Basically good, until I try to create a task with a date of my choosing. When creating a new task and bringing up the date picker the OK and Cancel buttons are covered by the on-screen keyboard, making it impossible to choose a date. Key presses go to the task title, not the date picker. Dismissing the keyboard also dismisses the date picker. So, the only way to set a date for a new task is to first create it for 'today' and then edit it afterwards. This isn't pretty.
