trivial criticism
The article makes pains to point out that Ubuntu doesn't create a separate home partition for user data. The article implies that this is is a shortcoming of Ubuntu. This is a stupid criticism.
Let us observe that no versions of the successful operating systems Windows and Mac OS create separate disk partitions for user data. Why not? Probably because it is a worthless division of disk space.
Disks fail, not partitions. Disk failure is something worth worrying about.
