There's another parameter (not that the software development process 
is terribly on topic): original verus additional code. 

Comparitively its much easier to write X thousand lines from scratch
and have a working system than it is to write the same number of LOC
against an existent code base and to have it work similarly well.

Please don't talk to me about buying houses.  We are still trying
to.  Our lawyers are still fighting and there are no winners (nor
likely to be anything but bankrupt survivors at this rate).

A dual Celeron 300A performs pretty nicely and can be had, decently
dressed for under US$1K.  (I've toyed with the idea of making and
selling these babies).

There's a scale in there.  There's also a question of engineering
process and control.  

A whole lot of Irix (eg the 4Dwm desktop manager (note: not the
windowmanager, but the Indigo Magic bits) and many of its little
clever bits, the finder, etc) came about because some engineer went
out and did something that he thought was "cool" (or often merely
helpful) and slipped it into the production code.  That said, a
whole LOT (millions of dollars a year of LOT) of SGI computers were
sold specifically because of such "cool" items.  This could never
happen at sites with heavier engineering processes, controls and
standards.  There is a very good and simple reason taht HP-UX is a
generally stable, predictable, and ever so boring OS.  They have
very good, enforced, and controlled engineering processes.  HP also
doesn't sell very many boxes on their "cool" factor.

<<And yes, the loss of "cool" at SGI in many ways has contributed to
their current hard times>>

Translation: Ferarri's don't just sell because they're fast.  They
also sell for the "cool genetalia waving factor", and given their
ongoing maintenance expenses, a whole lot of "cool" went in instead
of many "gotta have this or it will suck" factors.  (There is no
jealousy here just because I get passed by at least 5 Ferrari's on
my commute to work, or because the guy up the hill from me has a
Lamborghini, two Ferarri's, a Lotus and a DeLorean...)
