Fonts are one of my favorite thing to play with for eReaders. I have modified the ones I use adding weight and resizing them.
Fonts that I use
- Trebuchet - I use these on my eInk Kindles
- Amasis - I use this on my Tablets
- Gentium Book - I use this when I'm reading historical novels.
- Palatino - I use this when reading Regency novels.
I'm always looking for more readable fonts that work for me. There isn't many that do.
