I have no experience of 10.0 and 10.1, and others have already commented about them. I reserve an iMac Snow 500/1GB/40GB for use with a soundwave editor that is now out of production, and was never supported for higher than 10.3.2. Jaguar lacks some conveniences when compared with 10.3, but its stability and reliability have never been less than fine for me. It is sometimes an irritation that software for 10.3/10.4 may be explicitly stated as being unsuitable for 10.2, and ClamXav and SuperDuper! are two such programs, but Retrospect backs up entirely satisfactorily. The dedicated machine is fast in 10.2.8, and reliable for its solitary task. DW 3.0.2 and MacJanitor are supported, so I have little concern about housekeeping tasks.
