Often I see users opening up the time and date panel from the task bar to have a look at the calendar. It is fast makes it easy to work out what day of the week a date falls on. The trouble is that if you are looking in a different month you come perilously close to changing the date. Windows Vista improves on this and makes things surprisingly fast. Today I discovered that if I click on the date, it shows a mini calendar and clock, ideal for a quick calendar browse.
