For readability. I configured microb for a minimum font size of 20px. This works very well for most sites, as it overwrites the font sizes of the website. 20px is necessary for me to comfortably read on my N810. A minimum font size is not the same as zooming. Zooming increases the whole page and I end up scrolling horizontally all the time. Minimum font size just increases the fonts, but lets the page layout intact as it was designed. That's what I want. If a minimum font size could set for Tear as well, I would immediately switch. But at the moment microb is far more comfortable to me, despite its slow speed.
