This is a great tip submitted by Kush Patel: Converting currencies! The conversion widget included with the OS is good, but it could be better. This is what this widget called CurrencyConverter offers. The biggest advantage there is over the regular conversion widget is the possibility of converting many different currencies at once. It is very useful if you are planning a trip where you will go in many different countries. The standard conversion widget also only gives you precision up to three decimals while you can set this one to go up to five. This might not seem that important, but if you are trading currencies or stocks, it can make a big difference. Another thing that I noticed is that it seems to update to get the latest info more often than the widget from Apple. You can download CurrencyConverter here from Apple.com. Thanks for the great tip Kush!
