I suppose changing the name might help attract more attention to the
HP3000.  However, you should keep in mind that there are (at least a few)
people like me who react in just the opposite way to your intention.
Anytime a company changes the name or appearance of a product as purely a
marketing gesture, it annoys the heck out of me.  To take a very mundane
example, when the "health food" craze became popular, several breakfast
cereals with the name "sugar" in the title replaced it with "honey" or
"golden" or something else more acceptable to the health-conscious.  In my
case, though, I saw it as an attempt to manipulate through hype and so have
not purchased any of the aforementioned products since.  HP has already
taken steps in that direction with the incredibly ugly design and color
scheme of their new HP49G calculator (in an attempt to appeal to students
rather than their traditional engineering market).  I'd hate to see them
start messing with the venerable HP3000.  So, although a name change
wouldn't turn me against the 3000, it certainly wouldn't do anything to
endear HP management to me.
