Hey mayo,
FYI
I'm still running a PPC iBook on Panther with 126 applications, 67 utilities, OS 9, Windows XP pro, and Linux and it's stable. Sometimes I wish it would mess up so I could justify a new toy! Only one time in 4 years has this product given me a scare, where even Disk Warrior couldn't fix it. I inserted the TechTool pro CD and it brought it back to life. I follow Pendragon's Permission Prescription and eat an Apple a day.
Tony, I would tone down the sensitivity meter just a tad if I were you... Communicating via a Web forum and e-mail is imperfect at best. There is no immediate give-and-take so we cannot correct misunderstandings as soon as they occur. It's the nature of the medium when responding to a post to make some assumptions and try to cover all the bases at times... and sometimes the assumptions are incorrect. So It Goes...
As far as Leopard is concerned, I don't find it to be a problem OS at all. In fact, starting with Tiger (10.4) the Mac OS has been amazingly stable and trouble-free. I cannot recall a single problem that I have experienced that could be traced to the OS since I upgraded to OS X.
Pre-OS X? That's another subject... I had to spend significantly more time trouble-shooting OS 7-9. OS 9 was the best pre-OS X operating system but it still had its quirks. And like earlier Mac OS versions it was vulnerable to third-party extension conflicts. OS X (at least starting with 10.3...) is as good as it gets OS-wise. OS X really whacked Microsoft upside the head by showing how to get it right when it comes to designing a stable, easy-to-use operating system.
