Tiger uptime: 4 days
I was trying to see how long my Mac could stay up after installing Tiger. It only made it to 4 days.
Burning a CD in iTunes, it just stopped. iTunes stopped responding, Finder stopped responding, and I couldn't kill either of them, and couldn't shut the system down. Ended up having to power cycle. Bummer.
This is stuff that isn't supposed to happen when you have a Unix base...
