Okay, I have a question. I have just formatted my 40GB HD in a 4/36 GB split, intending to put OSX and the core iApps on the smaller partition, and all my other apps and data on the larger partition.
After loading OSX, and all the updates to this point, I am using 3.47 GB of the 4GB total. I plan on someday putting 10.3 on this computer, and I am wondering if I should reformat now to expand my OS partition to 4.5 or 5 GB. Regardless of this, is .5 GB of free space good for the OS? I planned on using the larger partition for scratch in PhotoShop, etc, but I am concerned about "headroom".
What is your opinion?

If your going in for partitioning your HD you may as well make a partition for the OS Swap file. I did this and the computer starts up quicker. You only need 400mb or so.

Anyway, you need, at the very least, 1 GB of free space on your System partition (think about CD burning, for example, which requires about 650 MB); and you should also consider that the /Applications folder may considerably grow in the future, due to new - and "heavier"! - iApps, and also new apps you install yourself (unless you choose to install them in a personal ~/Applications folder in your Home folder, moved to the second/third partition, à la Bombich   ): personally, I would give the System partition at least 10 GB (or 7.99 GB - < 8 GB - if you have an old, tray-loading iMac, etc.)...

Er, this is just plain crazy use of your partitions. If anything, you should do it the other way around - use the smaller partition as your Photoshop scratch disk, but install the system and applications on your larger partition. The system generates swapfiles of ~80MB whenever you fill your physical RAM so if you maintain your present scheme you will find yourself rapidly using all that .5GB of free space up and then suffering tremendous problems such as preferences being overwritten and piss-poor system performance.
Also, if you want to get the full benefits of OS X, third party apps should also be kept in the Applications folder so that you can use any Services they offer. Your current schema is not going to allow for this. I'd start from scratch if I were you and either generate just one partition, or two with one smallish one for use as your Photoshop scratch disk.
I have my 40GB HD partitioned into three - one large OS X partition (33GB), one Classic partition (5GB) and one Scratch disk partition (2GB). If I had the means to back it all up and start again, I'd just do two - one large systems partition (38GB) and one small scratch partition (2GB) - as it is, I'm wasting about 3GB of my Classic partition as I no longer use OS 9 for very much at all and I certainly never boot into it.

With your setup, why partition at all?

Well, I wanted to have OSX seperate from my data in case I needed a clean reinstall - I have memories from my OS10.0 days.
I ended up reformatting to 10 GB for the system and scratch, and 30 for everything else.

Well, I have my system partition set to 6 gig (with almost 3 gig free). I install all my "Apple" apps there. I have a separate partition for Virtual PC and one for X-Files (all those "other" OS X apps installed from other vendors and I've also place Classic here, since I don't use that too much). I then have a separate partition for all my data (and have moved my Users folder to my data partition).
This way, to backup my data, I just need to backup one partition. My VPC data files are on a separate partition and away from all my working files so the VPC drive images will be less subjective to fragmentation. All my 3rd party software is in one place.
Not saying its good, not saying its bad, it is just the way I happen to setup my system. Your Mileage May Vary.
