Not too bad but

It gets a little bit cluttered because each time entry for a task shows up seperately instead of allowing you to add a new start/end pair to the task. I might work on one thing for an hour and get a call and have to go do something else for an hour then come back and work on the original task a bit more before finding that I need to complete some work on something else and then coming back to the original task yet again. This means that my daily calendar shows up with the same entry 10 times and its not cluttered. Group them, show the total for the day/week/month and then let me drill down to the details if I want.
