New versions make some additions that can be significant for some users. It all depends on your requirements.
Abdulqadir Nashwan's resource was very useful.
In case you desire any of the following:
• Monte Carlo simulation for building better models to uncertain inputs
• Ability to compare two data files or data sets to ensure the data values and records are compatible
• Password protection of data and output files (encryption) to prevent others from seeing confidential information
• Improved and faster file merging
• Enhanced pivot tables with new features such as easier navigation and sorting operations
• Easier model specification in IBM SPSS Statistics Amos for structural equation modeling (SEM)
• Programming in SPSS Statistics with a Java plug-in
• Ability to import IBM® Cognos® Business Intelligence data into SPSS Statistics for additional analysis
• Exporting of output to Microsoft Excel 2007/2010
• Better scalability and performance with load balancing with IBM SPSS Collaboration and Deployment Services
• Single sign-on between SPSS Statistics client and server
• For security restricted environments, the option to run SPSS Statistics server as a non-root user on UNIX/LINUX
• Compression of data files for increased storage space
• Version compatibility to support new clients with old servers and vice versa, such as client V21 and server V20 OR client V20 and server V21)
For any of the above reasons, getting the newer version may be a good option. However, if the V21 is still giving excellent satisfaction then you can hold on for another upgrade.
