In my opinion, I feel OS 9 is still it's own beast with its own set of problems. I would give it a bit longer to get things worked out before adding it in with older OS's. Most of the problems with the older OS's have been worked out and fixes have been posted or work-arounds are readily available from many sources. People/companies are still having many unique issues with OS 9. I would wait until a bit after OS 9.0.1 is released and see what fixes are included and what solutions come down the pipe by then. Just my $.02 worth...
