I'm running Tiger on 6-year-old Macs AND it's an IMPROVEMENT (generally) over the OS 9 for which they were designed.

I have a dual G4 that I believe is approaching 8 years old running OS X Server and Kerio Mail Server. Only has 12 users on it but it runs better than the original OS 9. I used it to replace 4 Compaq Proliant servers. I will replace it with an XServe one day, but no need at this point.
