All those problems? What problems? The only "problem" is peoples' inability to properly maintain their disk integrity, doing all sorts of stupid things to their machines and installing all manner of crazy hacks; that's the "problem".
Mac OS X 10.2.3 is rock solid.
And even WITH "all those problems", that accounts for a very, very, very small minority of those who installed 10.2.3. Ever notice how it's the same people always having horrendous problems with their machines? Think it's any coincidence?
