Thats like Ford saying half of all fatal car crashes were caused by driver error and not by the car failing.
I have never, I mean NEVER put a patch on an AIX, Solaris, or Linux system and had it break anything! My time for test to production patches is a couple of days for a low risk, and at most a day for high risk. On the windows side of things three times last year I had a patch break something else (usually an application it would be SQL server, or ...) My time from test to prod is at least a week on critical systems and around a month on low risk.
Windows update is fine for the desktop but anyone who would update Windows without extensive testing is nuts..
No, it is NOT a highly contentious point. What is contentious is "which package system is better, RPM or Debian .deb"? But ANYONE who has ever dealt with both Win2k and either RPM or .deb knows full well that Linux wins hands down on this matter.
