In any case, whether more people are using 1024 by 768 or higher resolution, to accommodate the entire world, you should design based on the lowest screen resolution.
Roughly about 1% of the computer users are using 800 by 600 pixels resolution, it sounds small but if billions of users are surfing the Internet, the 1% will become some few million people using that screen resolution.
Why do people still prefer to use 800 by 600, it's because the font size is larger and easier to read. For youngsters or some adults who have good eyesight, they would choose to go for higher resolution, but for those who have weak eyesight, 800 x 600 becomes their favorite.
On top of that, not to forget that nowadays there are small sized laptop using 800 by 600 resolution, and this group of people is increasing at warp speed. Can you afford to lose these visitors?
A good design should work to minimize the problem for your visitors. Imagine if you were using 800 by 600, and you visit a website that fits in the 1024 by 768 resolution, you may have to scroll to the right to read all the text. You'll get pissed off by this.
Don't lose your potential customers just because you don't think from their angles.
Remember, your website is to cater to the visitors' needs, not your personal preferences.
