A while ago I had asked about your opinion about 10.4 on a 600mhz G3. Time for a happy user report (this book is parked in Munich where I go three times or so a year; thats why there was such a delay): install was successful, and even with measly 640mb ram, it runs properly, though it does get breathless quickly with too many open apps. Im sure more ram wont hurt a bit, so thats the next thing Ill do. But all in all, Im quite happy.
