Readability, to me, is the main issue. It is rare that I print out code any more. By breaking up long lines and indenting the continuation lines, the code becomes easier to read and understand: that means, in my book, easier to debug.
I used to limit the length to 80 charactes so I could print the code. I haven't printed a single line of code in several years, and now I am a little more relaxed about that rule. I still try to keep most lines under 90, but 2 or 3 extra chars won't do any harm.
What about him?
I'm not saying that our team works on small monitors with high resolutions, I'm saying that we use big monitors, currently 22" & 24".
My current configuration is 1680x1050 on a 22" DELL monitor.
Sure the resolution is high but as the monitor size is also above the usual you keep seeing thing on a normal size, no problem.
I can tell you that connected to the same computer I also have a 19" DELL with a resolution of 1280x1024 and I don't see any difference between them on the font size... I only have more workspace area on the 22" monitor.
