Prevent SSD wear by using SmartSleep

"I guess you're right for the laptop Macs ... Judging by the speed my 2006 iMac goes to sleep and wakes up"

Yup. Disabling "sleep & hibernate" mode only applies for laptop Macs. However, the way to verify this is NOT by user perceptions of sleep and wake, since your Mac can still be doing writes after it's seemingly asleep.

The correct way to verify is to look for existence (or lack thereof) of the "sleepimage" file in /var/vm/

And my Mac Mini indeed does not have a sleepimage file, so I guess this is only an issue for laptop SSD users. (Disabling "sleep & hibernate" was the first thing I did when I got an SSD in my laptop.)
