My understanding was that at least on the lock screen there was no easy way to distinguish between different calendars - I want birthday reminders to show up persistently for at least a week before the event, which is obviously undesirable for most other events.

If the lock screen gets/has that functionality, I'm not sure what the real difference between that and a widget is - except that mine displays on the home screen while yours displays on the lock screen.
