I think the right answer is that jruby alows us to have diversity and flexibilty to use java libs and take the high performance of multhreading and use some resources like java web servers like Tomcat and the VirtualMachine etc. There are a project called Ruboto that use jruby is main language to develop apps for android OS. http://ruboto.org/

We can not answer this question without knowing what you're "really" looking for. In general, for Ruby-ists used to MRI the "main" difference is GIL-free multi-threading (Ruby code can actually run in parallel utilizing your CPU cores). It's similar to Rubinius (also GIL-free) and is probably something that from time-to-time confuses Ruby developers if they have little experience with concurrency. This is usually not something you need to worry about (as popular gems are thread-safe), but you might hit it eventually e.g. with web applications in your own user code. Unlike Rubinius however, JRuby does not support MRI style C-extension gems, luckily most popular ones have alternatives or versions using Java-extension. The most notable difference you'll notice when trying JRuby out is that it's slower to start, however with a few tricks (jruby --dev) it's not that bad once you're using it for a while. ... all that being said JRuby is just Ruby and you can use it just like MRI.
