Favored Freeware: WORLDview Widget

[The WORLDview Widget is] a world map, presented in a Dashboard Widget, which displays all the countries in the world. It gives you the country map, the national flag, country coordinates, the capital, the continent, and photos from the selected country.

Pros: The WORLDview Widget provides quick and easy access to a detailed atlas of all the countries in the world.

Cons: The current version (v1.3) is a little bit slow when searching for countries. This is probably due to the quality of the map. Selecting a country via the “Select a country” menu provides no visual feedback, it will always display “Select a country.”
