I used to do html/css layouts very frequently just a few years back, and after tracking my hours to determine this, I found that coding for IE6 idiosyncrasies essentially doubled my html/css dev time. So I'd have a layout done and ready to go in Safari, Opera and Firefox (Chrome wasn't on the market then) in 4 hours, and it'd take another 4 just to get it working correctly in IE6. Luckily though, I billed hourly (so it was never really a problem), but it just amazed me to realize how much money clients were throwing away trying to support IE6 at the time.
