For now, I admit, it's a luxury. But when coding, it's REALLY nice to be able to have an IDE (the code) up on one monitor and a reference or distraction up on the other. Most IDEs are written with the assumption that they'll be used at near-full-screen size, and if you shrink them too much it gets a lot harder to read the code, so you have to keep them big; but often when coding you're also constantly referring to the Java API, or the MSDN for C++ stuff, or a google search for "hideous error 3245324334", too. Eliminating the constant flipping back and forth is just awesome.
