Eclipse is a new world for Microsoft� Visual Studio� developers, and getting started with Eclipse can be confusing. New concepts, such as plug-in architecture, workspace-centric project structure, and automatic build can seem counterintuitive at first. Learn about these and other differences between the two environments, so that you can begin to feel at home with Eclipse.

All integrated development environments (IDEs) share similarities because they're all built for the same purpose. But they have differences, too. Some of these can be attributed to application domains, but others result from the IDE design.

I use Eclipse for Java, Perl, Javascript, XML/HTML/CSS. Some its great for, others I use it for just because its nice to have all my shite done in one place.
