Using Panther with Clasic os 9

I was just wondering if there was any reason for me to ever use the classic os on my mac. All my adobe programs have an file that opens in os x and classic.....other than special applications that only run on os 9....is there anything I should know about os 9....or something I might enjoy in it?.......I havve only been using macs since os x....so I really know nothing about os 9...thanks a lot

If you don't have (or want) any apps to run in OS 9 then you don't need it. It was only special before we had OS X
