I agree. For years I coded in tiny, non-anti-aliased fonts. Recently I switched to an anti-aliased font at a larger size and the difference is definitely real and positive. Less headaches, easier readability, more distance between my eyes and the screen. Also, make your fonts brighter but maintain a medium level of contrast with the background.

I heavily disagree though that larger fonts cause you to write shorter methods. That's kind of ridiculous.
