Last year I did replace my SVN software repository with GIT.
Last moth I began to use GIT also at the office because I will be able to roll back the experimentations sometimes I do in my projects. The history of the Eclipse IDE isn't enough to archive the goal. GIT creates locally a full featured repository with tags and branches. Any time I may switch to a different branch, so I may work, at the same time, on the mainstream and on the experimental features.
