A long time Mac veteran has written an open letter to Steve Jobs, criticizing Mac OS X. His main points are:

• Installation of Panther takes 3 days
• Defective RAM isn't detected by the Installer
• Optimization phase during installations takes too long
• System updates can't be reversed. Only way to go back is to wipe the disk which means loss of user data.
• Millions of libraries are too confusing
• Fast user switching makes a well-known third party audio program crash.
• Something with customising audio-hardware
• No way to save configurations of Audio MIDI Setup
• Problems with USB audio hardware, especially after sleep
• Firewire drives with Oxford 911 chips don't work
• Windows can only be dragged by grabbing their top
• Files can't contain slashed and question marks
• Copying "_Icon" files sometimes hangs
• "Optimizing" should also "fix permissions"
