Hi, Egan --
Yes indeed, the fullnut display units are better than the halfnut display unit, due to less space between the segments. I have a 1980 HP-41C, a 1984 HP-41CX, and a 1986 HP-41CV. The fullnut 41C has the most "solid" characters; the fullnut 41CX has slimmer but taller characters, and the halfnut 41CV has the characteristic abstract-looking characters with too much space.
On reliability, I'll note that both of my fullnuts arrived via commercial air (USPS Priority Mail) malfunctioning and in need of service. Ultrasonic cleaning and some soldering by www.fixthatcalc.com restored perfect functionality. A collegue at work also has a fullnut HP-41C that exhibits the same symptoms as mine did. My halfnut 41CV was purchased locally and has performed flawlessly.
Perhaps a fullnut, with an occasional servicing, could give as many years of use as a halfnut model, but (almost?) all fullnuts are older than any halfnut -- the changeover in design occurring in 1985.
