* less context switches. In fastmail you do everything in popup windows where in Google you sometimes have to go to a separate task window. * very easy to modify individual occurrences of repeating tasks. Just drag or resize, it'll detach automatically. * the week view is sliding, ie you can view events from Wednesday to Wednesday. * much less clutter in UI and interactions overall.
