It's hard for me to imagine ever finding anything better than Ubuntu Mono, but for those who haven't found a love of their font-life, now might be a helpful time to relink to the one slant article I ever saw: http://www.slant.co/topics/67/~what-are-the-best-programming...
I like to code with about a 9 point font, in order to maximize the amount of code per screen without going too far into the illegible. At that size, the proportions of even a single pixel are large enough to make any anti-aliasing annoying. You lose the sharp contrast that every good font needs to have along its edges.
Mine too. Dina is my font of choice for now, also because it does a good job "to maximize the amount of code per screen without going too far into the illegible", among other things. If you code just with ASCII, maybe you'd like to try it if you haven't already.
That isn't what it looks like on my computer. I suspect this image has been resampled because even aggressive hinting wouldn't generate such rough forms at 11 pt.
The letter l on it's own at small font sizes resembles the number 1 in other fonts too closely. In fact, my default sans font (DejaVu Sans) has the 1 shaped just like the Inconsolata l. I'm sure it's something you get used to but I personally prefer the style used in DejaVu Sans Mono or Ubuntu Mono, where the l shape can't be mistaken for anything else.
The italics are amazing - very visible and distinct from the regular font, making it a great tool for validation. E.g. it's very noticeable when a CSS rule is not italic all of a sudden (misspelled). It adds a nice layer on top of colors to distinguish between different states.
ubuntu mono doesn't seem to scale well, at least on my tests in notepad++ on windows. Once I get to 12 point it starts acting like it's bolded. Source Code Pro and Consolas don't seem to have this problem.
I've always used Consolas since it's been out, but after seeing Source Code Pro, that does seem easier to read.
Ubuntu Mono renders superbly in Ubuntu, but I agree with you that it doesn't render particularly well on Windows; when on Windows, I sadly go back to DejaVu Sans Mono.
Don't know if it's only me, but I keep changing/cycling fonts and color schemes of my terminal every few weeks or so. Currently using Source Code Pro with ZenBurn. Will give Ubuntu Mono a try tonight.
I resist making any changes to my fonts/themes. I can spend hours sitting there tweaking them instead of just sticking with something I know (Menlo + Monokai for instance) and then just getting to work.
