I don't have to worry about OS differences as much. Also, the way jruby's is distributed is great. I can download it's entire history and easily and update it easily. It's trivial to move between different versions, keep them in sync across different systems, and not worry about screwing everything up. With ruby1.9 it's a different story. I admire the work that's going into ruby1.9. I'm just not sure it's going to be so easy to manage. I could try to deal with whatever versions happen to be in various package managers. I could maintain a collection of tar balls. I could maintain directories of different source trees. None of those seem like very good solutions.
