If safari works and is right for the job, why change? I think I've had to open chrome only a handful of times and that was a Java issue.
Kudos. Safari is becoming the new IE in terms of compatibility, web standards, and for workarounds required due flaws / bugs / oddities / whathaveyou. So by using Safari, like the IE users before you, you are helping employ an untold number of web developers. Using inferior products is actually good for the global economy.
