My dad was in his early 60's back in 92 when I put a T86 on his wall. He loved that thermostat as it worked well with his new (back then) V7 Burnham boiler. I have a pretty simple older 8000 vision pro tstat in his basement now living with us. He HATES that t-stat even though I have no problems with it,I'm well beyond 50 - will be retirement age this year and I have no issue with the controls!
I of course am probably wrong, but applying the KISS method works wonders with the general public.
You wife is more like the general public IMO. Keep it simple with up and down arrows. Even I like that the best.
