I still don understand what a widget is. Please clarify, in different words.
A widget is a small program very similar to an ipod touch’s app. It usually has a very specialized job for example a weather "widget" on your desktop would only tell you the outside temperature and the day’s forecast. They usually fill a "niche" market, meaning they are downloaded or created with a specific purpose in mind. Since they seem like small programs one would assume that they don’t take up much space but they do require a lot of your computer’s attention to run so if you have many running at once your computer may run slower.
