Month view. Faster and simpler than previous versions. For days where there are more than 6 appointments visible, you'll see a little red dot on the day (as you do on the 21st below).
Buttons in the upper right easily let you jump to the current day or select a day's month to view: these buttons are available on every calendar screen, making it very easy to move around. To make things even faster, all date selection and other mini windows close themselves and take effect with a click of the enter key. (16 of 21)
