I've just been playing around with my home setup, what I had wasn't doing it for me today. I dislike serifed fonts, I think they're a waste of valuable pixels. I had been using Arial, but my eyes must be going, it was getting a little blurry today.
So I'm trying Consolas for the first time. Interesting little font, though it seems to skinnify the right side of M and N a bit. I'll let you know.
