@media handheld refers only to those ancient tiny proto-html cellphones from years past which couldn't even really display web pages. The ePUB, MOBI, Tablet, community of vendors all said emphatically "H*ck no, we are not @media handheld devices!" because they were correctly worried that this would land them forever in a no-man's land subservient to "real" web pages.
With today's small devices with very high resolution displays we still don't have a good way to tell HTML how to display things "correctly" on large displays with relatively low resolution vs. small displays with very high resolution. And as a certified old fart my eyes would like to remind you that no, the answer is not just to make everything including fonts 2X smaller.
