I am calling it right now. Within ten years paper calendars may be obsolete. It will happen because of the explosive growth of electronic calendars and cell phones.  These devices or webware can hold anything. All the user has to do is remember to use it.

Gmail GCalendar allows users to send SMS reminders to their cell phones! Average everyday people will never forget anything anymore. These added functionalities are much better than paper calendars, which do not allow any reminders. Birthdays will never be forgotten, life will be so much easier without worrying when each birthday is.

Then we can get to more important stuff in our lives.
