Or unless you don't do much or keep much.
On this box 1TB drive for / and a 500GB drive for backups.
 > du -sh /home
42G     /home
 > du -sh .thunderbird
18G     .thunderbird

On another box with two 2TB HD's.
# du -sh /home
277G     /home

You can see how difficult it would be to guage the length of the piece 
of string for /home. Who know what they will require in a year's time.

As you can see using even 30GB for /home would be useless on my boxes.
Regards
Sid.
