    * Many VCL (Visual Component Library) and third-party components (usually available with full source code) and tools (documentation, debug tools, etc.)
    * Quick optimizing compiler also able to use assembler code
    * Multiple platform native code from the same source code
    * High level of source compatibility between versions
    * CrossKylix - a now discontinued third-party toolkit which allows native Kylix/Linux applications to be compiled from the Windows Delphi IDE, enabling dual-platform development and deployment
    * CrossFPC - a sister project to CrossKylix, not released and now inactive, which enables Windows Delphi applications to be cross-compiled from the Delphi IDE for platforms supported by the Free Pascal compiler.
    * Class helpers to bridge functionality available natively in the Delphi RTL
    * The language's object orientation features only class- and interface-based polymorphism
    * Delphi 2005, Delphi 2006 and Delphi 2007 all support advanced refactoring features such as Method Extraction, etc. [1]
