Actually, the points made by Geoff's friend actually supports the
argument for a common consistent software structure. It's called
_Standardization_. When you have multiple suppliers of something, be it
software, electrical appliances, telephone equipment, or just plain nuts
and bolts, if everyone is building things to work under a common set of
design guidelines (electrical plugs with 2 flat blades of a certain
size, with one round ground prong separated from the other by so much
distance, getting 110V of alternating current at 60 Hz, etc.) then
anyone who wants to build a device that can use that standard design can
do so and sell that product or service, and know that the customer will
actually be able to use said product or service. Having a common
structure for an OS does simplify the job for a software developer since
they don't have to write code to work under every possible variant of
the OS (including directory structure, configuration file locations,
system settings, etc.), and the customer doesn't have to recompile the
kernel just to get a particular piece of software to run. That might be
something that many people on this list may be comfortable doing, but
the vast majority of people in the rest of the world will NEVER be
capable of doing themselves.
Like it or not, most people view a PC as an appliance that they just
simply want to work whenever they need it. It's like the difference
between a 50 year old MG and a brand-new Toyota -- in order to drive the
former, you might need to fiddle with the carburetor, choke, or ignition
timing every time you want to drive the car, the latter you just get
behind wheel, turn the key, and you're off to the races. Most of the
time, I have to include myself in this group -- if I have work to do, I
surely don't want to spend several hours troubleshooting some
configuration problem, or access permissions, etc., just so I can get a
particular program to run -- I usually have better things to do.
