Pros
Pro The easiest to read
All characters are completely readable in the smallest size.
Perfectly usable in terminal and code editors in 12px text size.
Pro Hipster among hipsters
Even hipsters will marvel at this font, praising you as the new hipster lord. It is best at around 19px (tested on Mac). Overall, it has better readability than many default fonts.
Pro Characters readable even at small sizes
The characters in Inconsolata have a slightly "wide" appearance that aids in readability, especially at small font sizes.
Pro Excellent readability
Very clear, distinct characters with decent spacing make Inconsolata very readable.
Pro Efficient scalability
Inconsolata scales well without loss of readability.
Pro Slashed zero characters are distinguishable from capital "O" and "Q" characters
Inconsolata-g screws this up by replacing the slashed zero with a dotted zero. A dotted zero is better than a zero with nothing in it, but worse than a slashed zero.
Pro Open source
It's an open source font, meaning it's freely available.
Pro No visible character breaks
Inconsolata renders lines in TUIs without visible character breaks; apparently unlike Inconsolata-g.
Pro Widely available
Inconsolata is available in the package managers of almost every open source OS.
Cons
Con Pixelated
This is, of course, intentional; but it can be hard to look at compared to other smooth mono-space fonts.
Con Smallest font sizes hard to read
Fonts less than 11pt start to fail readability tests. 9pt specifically has an additional issue where brackets don't align.
Con Not really good in all font-sizes
Completely clean pixels, no anti-aliasing so its best viewed in (n*12) pixel size.
Bold font-weight is not really good because of small padding between them.
Con Arched braces
Too much arched braces, decreases clarity, touching characters almost.
