Another Dictionary Widget!
The dictionary widget that comes with every Mac is good, but it's not always the best. There are some words, especially computer terms, that are only found in constantly updated dictionaries such as the Wiktionary. If you try searching "iPhone", you won't find much in most dictionaries, but the Wiktionary will inform you right away. What is great is that just like Wikipedia, there is a widget for the Wiktionary. The only downside compared to the regular dictionary is that it only works if you are online. You can get the Wiktionary widget here from MacUpdate.
