Wow, I'm really surprised by all the 30" -in favors-?<p>I use 2 24" in monitors and love it. As for having to turn your head... that's a very minor concern if your keyboard and mouse are centered (or sightly off center) you can see both monitors fine.<p>For me I use textmate on one monitor (main) and have web-browser, Adium, Skype open on the second monitor - organized so all three are "on top". Works like a charm.<p>I have another box with a 30" monitor, but I use it mainly as a review station. Window organization is a bit of a pain on that large of a monitor on OSX.<p>I would have to agree that that for media (games, movies, video editing) the single larger monitor is better.
