Compare two Salesforce sandbox

As developer I always found it handy to do this by downloading file/type that I wanted to compare using Force.com IDE(Eclipse) and then use Winmerge tool to compare.

 I wonder if there any other way to do this so I figured out that some peoples are using Ant and some are using  Salesforce org compare.It is one of feature that reside in  Salesforce Toolkit which contains other features that I will play with it later.

Salesforce Toolkit

You start by choosing which org you want to compare

You need provide username and password for both organization.

It will take a while depending how big your org is.
The good thing is you can wait or you can just close the window.
It will send the result to your email.

It provide three color codes to indicate if there new file, different or match file.

Orange mean there difference, red mean the file only exist in one sandbox.

You also can download the file.

It's cool and user friendly tool.Compare to Force.com IDE and ANT, this tool require no configuration at all.

Also you can find an idea has been raised regarding this.
