Backup of split filesystems can be easier.  The traditional 
split-filesystem approach kind of separates things by use, and some 
people create a separate /home also.  The advantage of one big root is 
efficient use of free space on small drives.

I'm afraid it requires one to Use Math(tm).  gpart show will at least 
show the real capacity of a drive, instead of the diagonally-measured 
inflated units used by drive vendors.
