      • Positive:
            • Documentation is good (but out of date)

          • Jython is an improvement over Java in that it is concise, avoiding all the static typing
          • 69. Jython allows you to use both Java libraries and Python libraries e.g. beautiful soup
          • 70. Jython can be used interactively
          • 71. Don't need to recompile
          • 72. Features in Jython such as lambda not in Java
      • Python's Client Side strengths could be...
          • Powerful and simple language
          • 73. Rich source code base
          • 74. Build from server successes – seamless environments needed
    • 75. Python can't “beat” Javascript
      • Server side JavaScript will grow
      • 76. Developers need integration between client and server frameworks (rails/prototype)
      • 77. There is not enough reason to replace JS with Python on Client
    • 78. References
