After not having a computer monitor at home for the past year and a half -- I've been using the laptop screen instead, which has been a little sucky for doing design -- I went out and splurged on a 20" Apple Cinema Display. Jesus, what an amazing monitor; I concur completely with Justin's Apple display lust.
The first thing I did after getting the monitor hooked up was fire up kottke.org in Safari. At this point, I'd like to apologize to those of you who visit my site with a Mac and an Apple display (or a similarly bright and crisp display). Holy burning retinas! Seeing that yellow green color at the top of the site was like staring directly into the sun. When the page first loaded, I recoiled, fliched my head to one side, clenched my eyes shut, and threw my hand up in front of my face to prevent any permanent damage to my retina. My efforts may not have been quick enough...when I closed my eyes to go to sleep that night, a bright white bar bounded by a dotted line beneath pulsed on the inside of my eyelids, delaying my slumber for quite awhile.
So, apologies.
