I simplified it a lil too much. Linux and Apple are both app based systems. But tablets and phones are where apps took off. Linux apps are open source but Apple approves apps on their ecosystem. Android(apps) is linux based as well. All new tech was tens of thousands of dollars back in the day. Hell, new TV tech costs $20K these days.You need to go read up on what OSX actually is. It is not even in the same galaxy as "closed ecosystem that's built for tablets". What it really is? --->Unix! My 1st time seeing Unix was on a DEC engineering workstation that cost $30,000. My second time seeing an actual box running it was a Silicon Graphics engineering workstation that cost about the same. They were running advanced 3D solid modeling software and simultaneous 5 axis CAM programming software because at the time that's the only hardware and OS that was capable of doing the math, at least that was available for purchase outside of DOD or NASA. Mac OSX 10 is most certainly not a tablet OS. FYI, Linux is an open source version of Unix that runs on PC hardware, which by the way is what Apple is using these days. Wasn't always so, but it is now since PC hardware has advanced enough to run the real thing.
