Regarding the RHD Stopclocks: If I could have afforded one, I'd probably never started the project. See my first post specifically mentioning them. Still would additionally use the computer to take notes and store them for later reference. The metronome and process timer for the paper is just a side benefit.
Regarding MS software: I'd rather use non proprietary software myself. However as I work in an MS dominated environment, learning C# was the obvious choice.
Regarding not using a computer in the darkroom at all: I totally understand this position and respect that opinion. My dad is the same with not using sat navigation at all, but only relying on paper maps (and my mom as the navigator). After 40 years behind the wheel, he probably reaches his destination better than I would ever be able to even with a navigation system.
