Cons
Con Small 'l' (ell) is too similar to big 'I' (Eye)
You can tell the difference but need to concentrate on the letters.
See the word "Illegal" as an example.
It would be better if serifs are a little bit wider for the big 'I' (Eye) letter.
Con Smaller than other monospace fonts
Con Small punctuation makes readability difficult
In some programs it's hard to see punctuation marks, especially periods and colons.
Con Smaller then other monospaced fonts
Size 13 of Source Code Pro is slightly larger then size 14 of Anonymous Pro.
Con "0" glitch
The 0 (zero) symbol has a 'dent' on the left.
Con Exaggerated italics
The italicized version of the font is too slanted, meaning that italicized comments in code look really unbalanced.
Con Hard to distinguish [ and {
Braces [] and {} are very similar.
Con No Cyrillic glyphs
There are no Cyrillic glyphs in Envy Code R which may be an issue for Russian users.

Con Lowercase "w" is distracting
The lowercase "w" is a bit distinct looking due to the narrow nature of the font. This could cause a distraction to some users.
