I conducted a test today to see which one of my laptops boots up faster. I thought the results were pretty interesting so I thought I would tell everyone about it. Both computers are running Leopard and are on A/C power. I measured the time from the start up "ding" to when the clock appeared in the system tray. Here are the specs: MacBook (basically a factory base model MacBook) - 2.0GHz (Santa Rosa) - 2x512MB RAM - 80GB 5400RPM HDD The MacBook took 35.5 seconds to boot up. PowerBook G4 12" - 1.5GHz PowerPC - 2x256MB RAM - 120GB 5400RPM Hitachi HDD The PowerBook took 62.7 seconds to boot up. For some reason I was disappointed with the G4. I think I still like the PowerBook more however *I am going to up the RAM on the PB to 1.25GB soon. I'll perform another speed test then and update the results.
