More screen = better, but it can also become a distraction.<p>I don't want to get in to a pissing match about 'whose screen is larger' so I'm not going to spec my monitors but I've found that it works wonders if you stick two smaller screens rotated next to your main central screen.<p>I have things set up so the central one is for coding, the left one is browser, calculator &#38; IM, the right one is email.<p>When using linux it can be quite tricky getting this to work properly, especially if one or more of your screens are driven by an accelerated card. In the end I opted to drive all screens using the same nvidia driver, I found a cheap X1 board with a DVI connector for the third screen.<p>If I have to work on a laptop I feel like I'm looking at my work through a keyhole, and I find it hard to believe that I once earned a living using just a 12" screen.<p>You can hook up a third screen to a laptop using one of those usb display adapters ;)
