I have a G4 1.25 single processor, which is a dual bootable system. I currently have system 9.2.2 and system 10.2.1, but only work in system 9.2.2. I am considering moving over to system 10, but before I do so, I would like someone to tell me the main advantages that I will notice using system 10. I have asked a few people this already, but no one has really answered why it is any better than 9.2.2 there response has just been "It just is" which isn't much of an explaination. I need to ensure that my move to 10 will prove worthwhile. Also I am running logic 6.4 and so it would be useful to know what version of 10 it will run most stable on. Thanks in advance.
