Those examples sound they they could be spread out across several different
properties. However, if you did end up having a lot of different OS
categories, you don't have to create "subclasses" for every possible
combination; you can just allow multiple categories per OS and mix and
match however many categories apply to a given OS. Furthermore if you
really want to model a hierarchy between OS categories you can add
broader/narrower properties to the categories themselves (see also: phylogeny
In the end, its usually best to design simple schema that fits the data
that you have right now rather than complex schema to fit edge cases that
you haven't yet encountered.

I think it would be useful to organize operating systems into commonly used
categories. Its just a matter of whether this should be built as a user
type or added to the Commons.
