Google designed every bit of the font to be easy to read on-screen. The 68MB .zip download includes italic & regular variable fonts, plus 700 non-variable or static fonts -- you probably just want to install the 2 variable versions. *To me* the immediate BIG benefit comes with passwords -- using Roboto Serif it's instantly apparent if that's an I, 1, or l, & the same with O vs. 0. No more copy/pasting into Notepad, then typing 1, I, & l to see which letter matches -- YEA!
