Instead, display fonts of different sizes and have user pick one. No need for 
user to know or care about units or numbers or DPI, same as web authors 
needlessly fixated on pixels instead of the fact that personal computers are 
expected to be personalized, which means desktop objects larger or smaller 
than as shipped from the vendor.

DPI is nothing but a way to describe pixel density, and users shouldn't care 
about numbers, only higher or lower, good or not good, better or not better. 
Higher DPI _is_ better, because higher means more resolution, more accuracy, 
and more pleasing viewing, but only as long as naive application and web site 
stylists don't force to sizes that work only on lower density screens they're 
viewing during construction.

"The wise are known for their understanding, and pleasant
words are persuasive." Proverbs 16:21 (New Living Translation)
