I've read this thing a few times now, and the only section I find not too good is this:

Mac OS X 10.3: New networking scheme confusing for some users
Some users are none too pleased with Panther's new networking architecture, which prevents some shares from showing up on the desktop.
As evidenced by a number of reader reports, this can cause confusion from network users who can see a window on a shared volume, but cannot unmount the share via "ejection," not easily determine their connected status.
MacFixIt reader Alex Gray writes: "Under Mac OS X 10.2 and earlier, when you mounted an AppleTalk share by browsing AppleTalk Zones, the file server would appear on the desktop, and "Computer" as a server.
"Under Mac OS X 10.3, this has changed. The only time a server will show up on the desktop is if you enter its IP or AFP name directly in connect to server. When connecting via the 'Network' apparatus on the finder toolbar you can browse the Zones, albeit slowly, and then hit 'Connect' to the server that you want, which brings up an authentication window."
"However, when you do it this way the server will not show up on the desktop, or the Finder Toolbar, and there is really no indication that you are connected to the server. To get back to this point you would have to browse the Zones again and there is no easy way to eject the Volume. This creates problems if you are not always connected to the network, as when you disconnect from the LAN, there is the typical LAG, Spinning Ball, and then disconnect message telling you that you are not connected to the Server.
In the meantime, as a potential workaround, you can add shared folders) from a networked machine to be included in Panther's sidebar by selecting it and pressing Command-T. However, you still won't be able to "eject" the server.

I think that it is more than confusing. It has been changed a lot. See also:
