Wouter blogged about his favourite Laptop filesystem layout , just one filesystem , and some geeks think that's a bad idea.
Actually I can understand Wouter not wanting to have different /usr/ /var or other partitions on his laptop , the 20Mb left and 300Mb right you loose on different partitions are exactly what you want to use on your laptop, however isolating partitions also has it's benefits
My setup looks similar to this :
/ and altroot so you can run 2 distros, keeping my local data on a different partition so I can upgrade , switch distro etc.. and /opt .. for the software that isn't shipped as a package.
Obviously I use LVM so I can use these different partitions also as storage for virtual machines that can boot a different distro either on the physical or the virtual machine.
And obviously the rules for servers are different than the ones for laptops or even personal desktops for that matter
