Or flexibility for the matter... Say you partition 2GB for / and 4GB for
/alt... On day one, you receive 1GB in / and 3 GB in /alt, in day 2 you
receive 3 GB in / and 2 GB in /alt, you screwed..  Obviously this is
not a 'realistic' example, but the point it makes is very realistic.  It's
much easier to accomadate the data when it all sits on 'one' drive...
