I discovered Inconsolata two years ago or so, and it's been my go-to monospaced font ever since. I have it set to 11 points anti-aliased and it just looks gorgeous!
For your viewing pleasure, here is what my typical development environment looks like (anti-aliased retina 11pt Inconsolata):
I used to use Inconsolata ever since I came to know about it.
But, after the monospaced variant of Ubuntu font is released, I switched away from Inconsolata. It is a great font, but Ubuntu Mono is better looking for my taste.
i recently switched to ubuntu on one machine. that font was one of the best parts of switching. it's amazing how much difference it makes to the feel of the system.
