Specs
Ranked in these QuestionsQuestion Ranking
Pros
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
I, I, L, l, 1, O, 0, etc.
Pro Customizable OpenType features downloads
The website offers customizable downloads for editors that don't support OpenType features natively.
Pro Script variant
It comes with script variant for italics.
Pro Ligatures
The typeface supports over 120 optionally enabled ligatures for common coding tasks.
Pro Italics
The typeface comes with an italic version.
Pro Space
Space used by the characters has been carefully balanced to keep them light to read.
Pro Reading flow
The characters have been designed to flow into each other so that the font feels easy to read.
Pro Distinction
Specific care has been put to make programming characters such as 1, i, and l or O or 0 easy to tell apart.
Pro Wider than usual
As it's wider, this means there's more space for designing characters like "m".
Cons
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.
Con Not free
This font requires a purchase in order to be used. The cheapest version ('Basic') is 60 dollars. There is a free trial, though.
Con Wider than usual
As it's wider, this means a short adjustment period may be required. If you have a limited amount of horizontal space, the wider glyphs may be problematic as well.
