The question that wont die: What size partitions should I make?

[wrangled]

I have dual-boot laptop, 30GB Fat32 Win2000 and 70GB FreeBSD 6.0-R. I 
plan to use this for normal home desktop use (not as a server). I have 
512MB RAM.

According to this page:

   
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/install-steps.html

I should use:

   / = 100MB
   /swap = 1GB
   /var = 50MB
  /usr = rest (68GB)

On past FreeBSD installs, I would occasionaly do things as root, and ran 
out of space in /root.  Since then, on desktop machines (with 250GB 
drives), I would make / be 4GB.  On my lapatop, I wouldn't want to give 
up 4 of my 70 gigs if I didn't have to.  So I am looking for a realistic 
number that wont cramp me, and wont waste too much space.  I am planning 
on 1GB, so it will be big enough to hold the contents of a 700MB CD ISO.

I have no idea how much of /var I need, other than I like to install 
various packages to try them out, and I would not want to limit 
something like a webserver or email server if I chose to run one for 
limited use.  A friend took the default install suggestions for a 
machine he planned to do some web development on, and said his /var was 
way too small (they were new to FreeBSD also).  I am guessing 5GB for 
/var would allow me to run a mail-server (for personal use) and 
Apache+extensions for limited website developement

A swap of 1GB is fine, I'm not sure I've ever actually used any swap on 
my machines that had more than 128MB.

I want /usr to be as big as possible (obviously), so my primary user 
account will have as much space as possible in /use/home/<account>.

Should I use:

   / = 1GB
   /swap = 1GB
   /var = 5GB
  /usr = rest (63GB)

?

thanks!
