I have a 30 inch at home, it is awesome, I like to use it in addition to my laptop screen.  I run firefox on the laptop screen emacs on the big screen.  When you move to a large screen, window management become even more problematic.  Fitt's law falls apart at 2560x1600.<p>I recently moved to stumpwm, and I have been having a blast.  Stumpwm is a tiling window manager written in Common Lisp.  I tried xmonad and awesome, but stumpwm just made more sense to me.  I think that all of the tiling window managers are a bit clunky now, but they have a lot of potential.<p>The next time I see 30 inch screens for less than $900 on outlet.dell.com I plan to buy 2 and mount them in portrait mode.
