There's another thread with good suggestions now too
https://www.mobileread.com/forums/sho...d.php?t=142339 but I'd like to update my font preference.
In the first Touch firmware that supported new fonts, I disliked the new font Felbridge. However a later firmware included the ability to shrink the line spacing, and after I basically set that to zero it turns out that Felbridge is nicer than my previous favourite.
I'd formerly loathed Serif fonts, a longtime dislike probably created over 20 years of trying to read long texts on computer screens. Helvetica, Arial, etc just work so much better on screen for me. But I'd tried the Caecilia suggestion from earlier in the thread and was an immediate convert.
Unfortunately it turns out that font is NOT free, it's a commercial font from
http://www.linotype.com/1313/pmncaecilia-family.html and we shouldn't be using it without having purchased it ourselves. :-( So now I'm still looking for a similar font.
