OS/X, sure. For me, Mac hardware, not so much. Generally when a new Mac comes out it's already behind the curve... and then the go and cripple them by making them non-upgradable. Hell, aren't they even GLUING the Macbooks together now making them unserviceable? Between that, the chicklet keyboard, and the one-button touchpad (ugh! Don't suggest multitouch as a workaround), and you've completely lost me.
Linux - I work with it all day long, but on my own time it's Windows. Why? Photoshop and Lightroom CC, Adobe CS2 (I still use Illustrator CS2 - haven't had the need to upgrade to Illustrator 2015/CC), my embroidery machine, games, and 3D Vision. What, Steam is on Linux, you say? Well that's just great... how does 3D Vision work on Linux? Yeah I know there are a few different 3D Vision projects going on but I really don't want to spend more time fiddling with and tweaking my PC instead of actually using and enjoying it.
