When You Have Choices.

I am kind of shacking, between the choice of taking OSX or Linux as the OS in my ibook. This is the problem when one has too many choices. Thought OSX can meet almost every needs I have for a laptop. But I think the speed of Linux should be a lot faster. I've also considered installing both and have a dual boot, but that would make things seems more complecated but not simpler. So...what's gonna be?
