That's very true, if I took the startup time of Netscape as an example on my G3 running OS 9, I may say that OS 9 is slow as hell. But that is just about the only thing that takes a while to startup, whereas every other program launches almost instantly as soon as I click on the icon. It's not the system that is slow in most cases, but the programs that are. If Adobe, Microsoft, and others took more time to optimize and work on their coding, then programs like Office and Photoshop may run that much faster. If you simply go clicking around OS X itself and use many different parts of the system, you'll quickly realize that it does many things quite well and with great speed.
