Pros
Pro It's simple, beautiful, and stylish

Pro Great for your eyes
Monofur is very legible. Even after staring at it for hours, your eyes won't get tired.
Pro Letterforms are highly distinct
The font is very legible due to the distinguished characters it contains.
Pro Great readability
Equally well readable as Bitstream Vera/DejaVu Sans Mono, but with slashed zeros (aids with legibility).
Pro Easy on user's eyes
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.
Pro Clear differentiations

Cons
Con Lacks bold+italic
Monofur has a regular italic and bold typeface, but it lacks bold+italic. Syntax-capable editors can better display code based on function/class/context/markup work when at least 4 families are available to display.
Con Only characters from the Western charset work in many Windows apps
The font includes all characters for all European languages; however, in most programs using Unicode (such as WordPad or MS Word), only languages using Western charset can use this font. These include English, German, French, Spanish, and Norwegian.
Trying to use any languages like Czech, Hungarian (Central European), Bulgarian, Russian (Cyrillic), or Greek will make the font switch back to default font like Arial or Calibri, even though Monofur itself includes characters for those languages.
Authors didn't bother fixing the non-working Baltic / Central European / Greek / Cyrillic / Turkish character set for those years.
Con No bold version
This is not so great on a dark IDE, the characters tend to wash out, unlike something like Consolas.
Con Seems too wide at size 16
The letters become quite wide at size 16, impacting upon readability.
Con Doesn't work at size 10
Menlo displays as expected for size 11 and bigger, but doesn't seem to work very well at size 10. Issues include zero not being the same height as the rest of the numbers and Parenthetical Brackets not matching up perfectly.
