So, I have a PowerMac G5 that I'm currently using as a main Mac. I was thinking about moving to my late 2006 iMac with a Core 2 Duo 1.83GHz. It has a broken screen, but I can connect it to one of my ACDs. But is it really the right thing to do? Firefox will soon be discontinuing support for 10.6 and 10.7, and 10.7 is the max my iMac can run. After Firefox drops support, there will be no web browsers left for the early Intel Macs. But on PowerPC, we have TenFourFox. Should I stick with my PowerMac or move to my Intel iMac?
