I think the print problem occured on people's machines that run in root. Some OSX users like to do that because they don't like to deal with permissions. Foolish, but to each his own.
I have been runing safari since the first beta, no problems yet. The latest release fixes both the issues stated in the article. It even corrects the printer problem if it has occured due to the previous version.
Seing as how Mac users account for like 25% of internet browsers, I imagine a mass switch to Chimera will make IE a more unsuported browser since that efectively cuts off say 20% of IE's 70% market dominance.
Ahhh... I love pulling numbers out my ass
