The original install I got with the 10.0.3 version that came with my TiBook 400 was very similar to OS 9 in reliability and crashes, etc. After I reformatted the drive and re-installed 10.0.3 it ran very reliable. A few crashes, but they were rare. Now I have all my Macs on 10.2. (Since September, if memory serves.) None of my three Macs has ever had a crash with 10.2. Occasionally MS Entourage quits unexpectedly, but it has no effect on the system.
