Dude seriously, forget IE 6 and possibly even IE 7, i strongly recommend you avoid trouble with these. IE 9 is comming soon IE 6 is history, with IE9 IE7 will also be history. Don't trouble yourself with oldest browsers.
@mari8899 - in certain corporate and public environments, IE 6 is still needed to access key business software and web applications that were originally created when IE 6 was 1) a business standard 2) The most standards compliant browser of its time. Those days are long gone, but businesses and public sector organizations (like your local governemnt) are loath to spnd money upgrading these old web applications and software. Eventually though, the cost of maintenance and security will change the business equation and they'll upgrade. Until then, IE 6 still has a small, dwindling nich that some web designers and developers will have to cater for.
As BemDesign pointed out, the corporate (read bigger) world of commerce and finance depends on so many different variables than a small mom and pops shop or even a mid-size company like any given record label deal with that developer skills need to be fully encompassing... not just knowing the latest tricks and thinking that anybody using the net is using (at the moment) the latest Safari, specifically on the Mac.
I'm really glad I had to delve out of the ad world of cool motion graphics and niche sites to a more global market because as other companies grow, they are relying on markets, not technology, to boom their business. That being understood, it's about knowing a target audience and how to reach them no matter how old/out dated their tech may be.
However, I will relish the day when HTML emails have gone by-by and browsers automatically update themselves (let all the privacy and security gripes cease.. don't put information you don't want shared on the net)
So, I hear ya about losing that 8.3% of IE6... but let's go for broke and say forget IE altogether and choose Firefox or Safari.
