Improvements across the board within the operating system and support from numerous vendors have made OS X a viable upgrade. Internal improvements have brought the performance and reliability up to professional levels, while software from such vendors as Canon, Epson, and Hewlett-Packard make compatible a wide variety of printers and scanners. As soon as 10.1 was released, we upgraded our Dual G4/450 with nothing but positive results. With multiple hard drives on our system, we're able to dedicate drives for booting into either OS 9 or OS X, thus ensuring backward compatibility.
However, since upgrading over a month ago, the only times we've needed to boot into OS 9 was for using a FireWire card reader (for reading compact flash cards from a digital camera) and only because the drivers aren't yet available. But you don't need a high-speed G4 to use 10.1. It's now become the default OS on our PowerBook G3/400 (FireWire model), responding quickly and running reliably. Airport networking works flawlessly, and Internet and intranet access is rock solid.
In addition to performance improvements, Apple has added DVD-video playback. Since OS X is a true multitasking operating system, you haven't really watched a DVD until you've made it a half-size window in the background while checking e-mail, shopping at Amazon.com, and copying files at the same time--without skipping a frame. iTunes for OS X will play and encode music, as well as burn audio CDs using an internal or external CD-R/RW drive. If you need to burn data CDs, simply insert a blank disc. OS X will detect it, and ask how you'd like to format it: Mac/PC data or audio CD?
Additional improvements in AppleScripting, a customizable dock, video card and printer drivers, and networking add to the appeal. One important missing feature is the ability to print to a remote USB printer. With OS 9, Apple included the USB Printer Sharing control panel, which allowed remote Macs to print to any USB-connected printer on a local Mac. This worked flawlessly for us when printing from our PowerBook to an Epson 1280 connected to our G4. However, there seems to be no such facility for printing to remote USB printers under OS X. Aside from that, OS X 10.1 on a contemporary Mac is a solid performer and a glimpse of how things ought to work. --Mike Caputo

OS X best ever2003-01-29buy it and never be disappointed!
Stable but Often Slow2002-11-14However, I would not suggest OS X on a G3 unless you are ready for slow resizing and tediously long launch times.
Indeed, even though it is slower, I feel that I am obliged to use OS X on my 600 MHz iBook - not because Apple is phasing out "classic" support. The only thing that truly binds me to OS X is that it is much more stable than OS 9. However, seeing how good things are coming with the new ideas from Apple as they update the system, I would suggest keeping an eye open. Perhaps OS X will speed up soon.
good... needs improvement in speed2002-10-02
X marks the spot!!2002-08-28Once you've been hooked, try OS 10.2, which is known as Jaguar. Too many great advancements to list, but you won't be sorry!
