I was just fooling around with pbs after the Tiger update and restarted my pbs, old PB G4 Titanium 550mhz/60GB 7200RPM HD/1GB RAM and my 12" PB G4 1.5GHZ/5400RPM HD/1.25GB RAM. The Tibook started up something like twenty seconds or more faster than the PB? How can this be? Is it because the Powerbook 12" has a "slower" Toshiba GAX hd, 16mb cache but 5400rpms? And the Tibook has a faster Travelstar hd, 8mb cache but 7200rpms? I'm astonished. The Tibook seems mighty fast to me... how weird is that?
