I left Apple last year after nearly a decade of using Apple products. I have a Zenbook Prime running Debian unstable now. I find Gnome Shell just as easy to use as OSX. In fact its more functional in many aspects like how quickly I can get to the things I'm looking for. That said, there are pros and cons to using OSX or Linux. But I don't feel like I'm missing out on anything. I think people should use whatever floats their boat.
