Don't partition MacOX drives. No need to.
There is absolutely no reason to partition a single hard drive so it has a separate swap partition. A separate swap partition is thought to increase performance, but that only works when the swap is on a separate drive. There really isn't any reason to have separate System and user partitions.
what about minimum block size?
My reasons for partitioning before was the minimum block size-- partitioning created smaller blocks. I would think with all the thousands of itsy bitsy files that *nix based OSes have, this would still be a reason to partition. You seem rather worked up about this, so please note I am not challenging you, I am attempting to improve my knowledge. Please let me know what you think.
what about minimum block size?
The minimum block size is 4K on HFS+ disks (well, it can be chosen differently when you format the disk, but I've never seen that happen). In the days of HFS, you could only have a maximum of 65536 blocks on a disk, so the bigger the disk, the bigger the block size. But no such limitation is present on HFS+ disks.

thanks-- did not know that!

Actually, there is a limit to the number of files on an HFS+ disk. It is 2^32, so around 4.29 billion.

A separate swap-partition reduces the fragmentation in the system and user parts of the disk. Yes, I know that Mac OS X automatically defragments some files nowadays.

"There really isn't any reason to have separate System and user partitions."
That's a pretty ignorant thing to say. You may choose to go with a single partition, but if you had any clue about using OS X, you would know that there are many good reasons for having multiple partitions. And separating the system from user partitions is one of those good reasons.

So then you should mention the good reasons. Why should I seperate user data from "the rest"? This is already done. It is called home directory...

There are multiple reasons. - Avoiding the swap generated disk full errors that frequently destroy user prefs and data. - Much easier re-installations. - Data protection in event of serious disk structure problems.
And those are three of only the most obvious reasons. More valid reasons do exist. I always have a minimum of two partitions, even if I'm not doing anything fancy. "And by forcing the swap file to use a specific area of your hard drive you lose the ability of OS X to move often accessed files to the hot area (fastest tracks on your hard drive) automatically." Only semi-true. If your swap file partition is over 10GB, you get the exact same hot-file capability. And given the naturally defragmented nature of swap disks, it's not much of a problem to begin with. But I personally don't give swap its own partition. From my point of view, it's too little or no gain for much too much work, and should only be done for educational purposes. But separating /System from /Users seems like an absolute no-brainer to me.

Aside from all the other reasons people have put forth for and against partitions, how about this:

Multiple partitions on a drive is an anachronism from the days of MacOS 9. It is not totally without reason. I have several partitions on my drive; one for beta or in testing OSes; one for Linux; one master "working" OS and data; and one with an image for CCC to copy to client machines. I could put them all but the master on a FW hard drive(s), but I prefer to have them all with me wherever I have my powerbook for use as the mood or need strikes me. However, I do have a question: I have heard that Apple's hot-file-adaptive technology and prebinding stuff only works on a drive with one (user-created) partition. Has this changed in 10.3 or .4, or is there an actual penalty for using more than one partition?

"I have heard that Apple's hot-file-adaptive technology and prebinding stuff only works on a drive with one (user-created) partition."
Untrue. The hot-file-adaptive technology kicks in on any partition larger than 10GB. So if you partition your drive with partitions smaller than that, you'll lose hot-files. Otherwise, not.

In addition to the posts above, here's another reason. Placing your iTunes, iPhoto, iCal, Address Book, Bookmarks, etc, etc, whatever you want, on a separate partition that has ownerships turned off has many benefits. This is the easiest way to share these libraries among multiple users (like an entire trusting family) on your computer. And no, "sharing" them via their respective Preferences does not accomplish the same thing. Everyone should be able to change the libraries.

The only reason I split up my main disk into two partitions last clean reinstall was that booting to OS 9 was killing my system, forcing me to fsck constantly. No matter what I did, the simple act of booting to OS 9 would often hose my main disk, causing the dreaded "?" on boot.

I have three seperate partitions on my system— one for the system, one for my data (symlinked to /Users), and one for my media (symlinked to ~/Movies, ~/Music, etc.)— because:
