I wanted to know if i should use RVM? I have been using rails more and
more and more now and am looking to keep ruby and ruby gems better
together. Is it worth using RVM? And what does it acually do other
then able me to swtich between ruby 1.8 and 1.9?

2 important things it does for me are:
1) I make a gemset for every new project or testing with a new Rails version etc.
So every time, I have a new, clean gem environment (example below)
2) it allows me to install multiple ruby versions, in my _local_ home directory, without worrying about the version that could be (or maybe not, I don't care) installed by root in the central /usr/.. directories.

Example of using rvm gemset : with a new gemset it is really easy to bootstrap a new Rails project, without interfering with the existing ones.
<code> peterv@ASUS:~/data/temp$ rvm use 1.9.3 Using /home/peterv/.rvm/gems/ruby-1.9.3-rc1
peterv@ASUS:~/data/temp$ rvm gemset list
gemsets for ruby-1.9.3-rc1 (found in /home/peterv/.rvm/gems/ruby-1.9.3-rc1) contact_app global
peterv@ASUS:~/data/temp$ rvm gemset create fancy 'fancy' gemset created (/home/peterv/.rvm/gems/ruby-1.9.3-rc1@fancy).
peterv@ASUS:~/data/temp$ rvm use 1.9.3@fancy Using /home/peterv/.rvm/gems/ruby-1.9.3-rc1 with gemset fancy
peterv@ASUS:~/data/temp/fancy$ bundle install Fetching source index for http://rubygems.org/ Installing rake (0.9.2.2) Using multi_json (1.0.3) ... Installing uglifier (1.0.4) Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
peterv@ASUS:~/data/temp/fancy$ vim config/database.yml
peterv@ASUS:~/data/temp/fancy$ rake db:create # will create fancy_development and fancy_test databases
peterv@ASUS:~/data/temp/fancy$ rake environment # this should return without errors </code>

You can even streamline this a bit more by putting a .rvmrc file in your project folder:
/myproject/.rvmrc
rvm_gemset_create_on_use_flag=1 rvm use <rubyversion>@<gemsetname>
RVM will automatically switch to the proper gemset and ruby version as you "cd" into the project folder (or out of it). There's a lot more options available in the documentation.

Vagrant is really nice, but I see it more as a solution to test your production environment locally than to manage gems or ruby versions.
Those VM images can be quite big, but are great to use as a staging server to make sure your production server will be able to run your Rails app (or an update) without any problems. Setting up your production environment on a virtual machine (a staging server if you want to call it that way) is great, especially combined with Chef. You can be fairly certain that your production server won't go down because of some incompatibility or different/lacking dependencies between your e.g. OS X machine and your Ubuntu production server.
