SpeedoMeter

Yahoo! Widget Engine was created to offer users the chance to use numerous apps to meet their precise computing needs, without worrying about RAM or CPU usage levels. Such a handy widget is SpeedoMeter, meant to monitor bandwidth usage.
SpeedoMeter can be quickly set up on any computer where Yahoo! Widget Engine is already installed (otherwise, the widget cannot be used until the platform is installed) and it displays a tiny window where the download and upload speed values are constantly updated.
Unlike other similar tools, SpeedoMeter comes with an analog representation of data, and makes the host PC seem old-fashioned and vintage-looking, adding a touch of style to the desktop. Also, those who are not satisfied with the default coloring can modify the text color and font type so that the widget integrates smoothly within the OS theme.
The Settings section of SpeedoMeter can be accessed whenever users want to adjust the update interval and span size used within the main window of the widget. The opacity level of SpeedoMeter can be changed as well, and users can set the widget to stay on top of all the running apps, at all times.
In addition, SpeedoMeter can also be used to restrict the maximum download and upload speeds to help users make sure they do not exceed their monthly limit.
In a nutshell, SpeedoMeter is a Yahoo! widget that can meet the bandwidth monitoring needs of any user, without needing to rely on complex or costly software.
