Mac OS 10.1 is noticeably faster, especially if you are running classic applications. The DVD player runs much better than the OS 9 DVD player. I can work in a foreground application like Mail or OmniOutliner while a DVD plays smoothly in the background. I'm a bit disappointed with the Microsoft Word test drive. There seems to be 2 ways of displaying text in OS X (someone will send me a note with the 2 different API names). One text display method produces ugly anti-aliased text like that found in OS 9, another produces amazing beautiful, highly legible anti-aliased text. Word displays some rather ugly text. AppleWorks does the same thing. I'm still going to do all my writing in TextEdit, OmniOutliner, Pepper or Mail. Just because I find it more comfortable to look at better rendered text. Otherwise I start concentrating on the letterforms and I get nothing done. Another nice fix in 10.1 is that I can just put my laptop to sleep, plug-in an external monitor and when I wake the machine the monitor is active. This worked in OS 9 and I used it a lot, with 10.0.x a restart was needed. My digital camera is now supported as well. The two things I really want now are new drivers for my HP Deskjet, so I can use the duplexing unit, and USB Overdrive so I can use all the features on my optical trackball.
