Try it and if you like it better switch.
OSX is a solid system because it's almost pointless to write a trojan or virus for it. If you want your message to be heard you target windows. If OSX was more widely used than windows the majority of them would be wrote for OSX.
You say it's pointless but correct me if I'm wrong, the Mac's market share has definitely gone up in the past few years so it may not be as pointless now or perhaps some time in the future?
