From: "Frank Haber" 

BobC gave you one soothing answer.  Another, probably equally safe answer: 
It will gain you nothing for a while; might even cost you some with some
software.  Eventually, it'll gain you lots.  You get to choose when you get
on the bus.  This is better than Communism, yes?

Looking at the other side of it, I remember when people actually said, in
1982, "Why move eight extra bits around when it's all just character
data anyway, one byte at a time?  That's right, they were complaining about
the 8086 and 68000.  I can think of four or five reasons off the top of my
head why the above statement is, well, just monumentally pinheaded.

Then there's Gates and "640k is more than enough."

What may take the cake is a peace of Remington (Rand) puffery ca. 1952 that
I once read*.  It implied that no computer could be a real computer unless
it used a shared address space for data and code.  In other words, some
boffin had convinced the publicist that self-modifying code was an
architectural requirement for a "real computer."

No evidence, but I'm pretty positive, since I had a discussion about it
with an  RCA computer engineer, round about 1960, and he remembered the
same brochure, and laughed along with me.
