Resolution debate

I’m just at the start of redesigning my site (gonna try and get some side business designing and developing sites for small businesses and such) and I was curious…

how many people still design with 800*600 in mind?

now I know no-one here still uses this resolution, in fact I struggle to think of anyone who does, but I was just curious do you think it professional to design for 800*600 and include everyone in the site…or do you just design for the resolution you think best?
