Here's a version with slashed zero (there's also another version with dotted zero from the same author): http://blog.cosmix.org/2009/10/27/a-slashed-zero-droid-sans-...

Agreed. I use this font in vim at work because (believe or not) it seems to be the sharpest on my crappy LCD monitor at work. I was using Bitstream Vera Sans Mono before though which I love.

+1 for DSM.

I use the solarized vim/terminal color scheme so from syntax highlighting I can tell the difference between the O and 0 but I can see why it would be a problem.
