A few weeks ago, I posted about wanting to downgrade to Panther ‘10.3′ on my G3 Blue and White PowerMac, however, I’ve since changed my mind for the following reasons:
1.) There are many Tiger only apps out there, mainly Bean, Adium (though previous versions support 10.2 and 10.3), etc. I also suspect that Panther will be dropped for the most part in apps shortly after Leopard’s release.
2.) Security-Panther will likely be discontinued in terms of security updates prior to Leopard’s release. This would follow Apple previously supporting a maximum of two versions of OSX at a time (in security updates).
3.) Tiger is likely the last release of OSX that officially supports the G3 processor, and thus, having the last release would be beneficial.
4.) WebKit-While many use non-WebKit based browsers (i.e. Shiira, Safari, etc.), Tiger has a newer version of WebKit than Panther.
So, those are my reasons for staying with Tiger..
