Tablets were added to the mix; I never used my iPads much, but did use my Samsung Note tablet a lot
This has been my experience too. Stylus technology and software that utilizes it has improved sufficiently in some places -- am hoping this trend will continue. The issue of how to carry a stylus without losing it doesn't seem to be well-addressed yet though IMO.
The specific Windows OS Tablet I've tried is a 12 inch Samsung Galaxy Book.
Partly my switch is about eyesight changes and monitors. I really really like big busy monitors, but the brightness overwhelms me now after a few hours
I don't typically last that long. I've coped by using an e-ink reader for certain activities (unfortunately, this technology is really taking a long time to develop nicely), staying far enough away from displays (not easy for a tablet one is holding), reducing exposure, using a single display, keeping my code within about 80 columns, etc.
One thing I found that helped on the hardware end of things was Samsung's OLED displays. This doesn't really help for external displays (too expensive / unavailable), but for tablets and phones, it seems to be less problematic on my eyes.
I learned about eye issues a fair bit from: https://ledstrain.org/
It appears people suffer for a variety of reasons and there doesn't appear to be a single practical "drop-in" solution, but there are many ideas there to learn from.
