Best partition size for Ubuntu Root

> I no longer remember the rationale for having a separate / and /boot
What I do (roughly):
1GB for /boot
10GB for /
10GB for 2nd /
10GB for 3rd /
3GB for swap (I have 1GB RAM, want enough space to hibernate)
...rest of disk for /home
The reason I have /boot seperate from / is that I have three different
/'s, but only one /boot (and so only one grub installation). Right now
I have 6.06, 7.10, and 8.04 in my different / partitions.
When I installed Hardy I copied all contents of /boot to my home
directory, I let Hardy install the way it wanted on /boot and one of the
/'s. Then I copied the old /boot contents back, and edited
/boot/grub/menu.lst give me my old Ubuntu versions, and I edited
/etc/fstab to mount /home.
This is for my laptop, my primary machine, the one I mess with most.
For servers I like exactly 2 / partitions. I set up menu.lst to boot
from either, I put the OS in both. Now, before I do anything scary that
might mess with correct function, [Label A Here] I copy the current /
across to the other. Then I do the kernel upgrade (or whatever) and
hope things work. If they don't, I can immediately boot back to the
backup. If it seems to work, I leave things as they are, keep an eye on
them, and if a day later I discover a problem, I can still revert with
little problem. Finally, when I am about to do something scary again,
when I finally trust the most recent upgrade was good, I start over
[goto Label A above].
Having a single boot (and single grub install) is necessary to boot back
and forth this way.
