This may come across as a rant, but I seriously want to know if there is a valid reason for this.
One of the great things about Windows 7 is I can update just about anything, even video drivers, without rebooting. Now I have a Mac Book Pro running Snow Leopard and I reboot for anything that involves Quicktime, Safari, iTunes and it would appear fonts. What is up with that? I thought all the Apple fan boys teased the Windows users about having to reboot so often with all the updates, when it certainly seems to be the other way around now.
Is there a valid reason for why Mac OS X needs to reboot so much? What is so fundamentally wrong with the OS that it doesn't allow updating without a reboot?
