Write thin to write fast
On a related note: At one point I switched to working exclusively on a laptop and after a while realized that the smaller screen had forced me to write better code. I wrote smaller methods, made smaller files, kept my concepts together, the whole nine yards. I even wrote better tests since that helped me keep my work small.<p>It didn't last; I'm writing this on a 27" monitor, but I think that has more to do with bad laptop ergonomics than space.
