I was able to upgrade to WordPress 2.0 without too much trouble. I had to install some plugins in both the new and old WordPress software to do a WordPress to WordPress import, but otherwise it was fine. The default theme doesnt stretch, which makes code samles look somewhat horrible, so I opted for this basic one instead and thyen just changed some color values in the CSS. I have a theme that I designed that I want to integrate, but I will have to find the time, so for now this is going to have to do.
