I agree that the TI59 sits between the HP-67 and HP-41C with respect to capabilities, but it was far behind both in terms of quality and usability.
In the early 1980s, three of us from my office spent a week in another office of our civil engineering company helping them finish a big hydraulics/hydrology master plan for a 90-mile-long irrigation canal that they were way behind on. I was handed a TI59 to do some hydraulic calculations using a program that another engineer (since departed) had written.
Unfortunately, the program had apparently not been tested by anyone (including the author) and it was buggy. Fortunately, I had his notes and the manuals to the calculator, so I attempted to fix it. ARRGH. I ended up writing my own program for my HP-34C (the SOLVER was a BIG help). If I had owned a 41 at the time, I probably would have used that instead and incorporated a programmed root solver…this was pre-Advantage Pac.

What were there other impressions you got from the iPhone app? Does it have, like 'Legendary 67' a mag card library you could build?
