RVM has a lot of uses. Ultimately, it will be useful to all Rubyists, but what is your favorite use of RVM? Remember that RVM not only allows you to install multiple versions and implementations of Ruby, but it also has power features like GemSets and testing on multiple versions of Ruby.
The best way to test out Rails 3
- I am using rvm to install ruby-1.9.2-head to test out Rails 3 whilst having ruby-1.8.7 running parallel for existing production code.

Keeping Ruby up to date
- You never know how quickly a distro will patch Ruby, or what they've done to it. I like to use RVM to have more control over which version and patch level of Ruby I'm using. I could be installing from source manually since I generally only use one version of Ruby, but RVM is just easier.
