Joomla 1.15 vs the new Joomla 1.5 which should you use?

I like to try and make things easy to understand for the average person...so you don't have to be a techy like me to figure it out.

There are many differences between the old Joomla and the new Joomla 1.5 but for the purpose of the average person here it is:

• The old version of Joomla has a huge amount of components and modules available many of them are free.
  
  
• Joomla 1.5 will have much more advanced components and modules available as the Joomla 1.5 system was re-written from scratch and is much more flexible and robust than the old Joomla and Mambo systems. But there are not that many available as of this writing.

• It seems many of the Joomla 1.5 developers have chosen to charge for their new components and modules but with the functionality they provide it's usually well worth the price.
  

• There are very few Templates currently available for Joomla 1.5 where the previous version has hundreds available and most are free.
  
  
• The old Joomla version would be a good solutions if you need to have the functionality of one of the available components...as an example Mosets Tree is a great directory solution as of the day I wrote this the Mosets Tree wasn't available for the new Joomla 1.5. SO if you want to build a site with a directory you may want to use the old Joomla with Mosets Tree.
  
  
• Mosets also created a nice Real Estate component called Hot Property which is only available for Joomla 1.15 series, so if you wanted to quickly create a Real Estate site where numerous agents could sign in and upload their latest listings for sale...you would most likely use the previous version of Joomla and something like Mosets Hot Property. BTW- I have purchased it and used it and I like it for it's simplicity and functionality.
  
  So in a simple nutshell the new Joomla 1.5 system is a much better system in the long run but for available plugins you may want to use the older version for now to get the components you need to make your site do all the things you want.
  
  Generally once you have a site up and running as long as you update to the lastest release of your version you will have the best chance at keeping your site secure, there may be no need to go to the new Joomla 1.5.
  
  Just like someone using Windows XP, if it's doing everything you need...there is no reason to go to Vista.
