Apple Menlo vs Code New Roman

Equally well readable as Bitstream Vera/DejaVu Sans Mono, but with slashed zeros (aids with legibility).

Characters are very readable. They have consistent widths across all weights as to not break up words. Commonly used programming symbols such as various kinds of brackets are made easily discernible from each other and various punctuation marks are made bigger than normal. This makes them especially good for programmers who keep staring at code for hours.

I, I, L, l, 1, O, 0, etc.

Code New Roman is published under SIL Open Font License making it completely free.

Code New Roman seems like a mix of Monaco and Consolas, but looks very well on retina monitors.

It's comfortable for the user to read Code New Roman for long periods. OpenType features include hanging or lining numerals (slashed, dotted, and normal zeros) as well as alternative shapes for a number of lowercase letters.

You can download and install it on Windows vista or higher (for cleartype technology support) and Mac OSX.

Code New Roman offers Regular, Bold , Italic, and Bold-Italic typefaces.

Code New Roman has been tested on cheap Dell Inspiron with Ubuntu 14.04 installed and looks great on gtk-based apps such as Sublime Text, Geany, and TextAdept. It's also great on Qt-based apps such as KDevelop and Spyder. For electron/nwjs-based applications, it looks great on Visual Studio Code and Brackets, but has yet been tested on atom. However, it looks horrible on Swing-based apps such as Netbeans or Jetbrains' IDE.

Code New Roman is available in English.

This means that jaggies are reduced, making the line smoother.
