...Also, 20% is a huge number of people who now see a horribly designed website that you need to scroll on to read. 20% is an incredibly large number of people who now are frustrated when they see your site. There is absolutely no need for a portfolio site to be this wide.
Perhaps you misunderstood my point. I was actually backing up your original claim that "surprisingly enough, many people still do use 800x600" with actual supported data. I simply pointed out that the trend was moving towards 1024X768 (on average 2-3% per month if you look at the data). Having said that, 20% is definitely a HUGE number of people and you'd be crazy not to design a site which supports that audience.
