I dig the vertical monitor. Using one of those as a second screen plus switching to xmonad has been the most positive change I've made to my own working environment in the last year. Code, websites, anything text oriented - shorter lines are easier to read and comprehend
How does a vertical monitor work with sub pixel rendering? http://en.wikipedia.org/wiki/Subpixel_rendering . Does linux do sub-pixel rendering? Does OS X turn it off when a monitor is rotated to vertical?
