I'm only a (very happy) user of WriteRoom, but my comments should also be taken with a grain of salt.<p>I find WriteRoom to be extremely pleasant, in a way that OmniWriter isn't. The experience of OmniWriter is nice, certainly, but it's not any more or less pleasant that WriteRoom. The pleasantness of WriteRoom comes from the obliteration of distractions. I can add nice imagery (which I don't) and a great soundtrack (which I do) on my own.<p>(To be clear, I don't think anything negative about Omniwriter, but it's not my kind of pleasant.)
