So it has an Apple Mac like look on top of Linux.
That is not far from what Apple did tens years ago. They placed an Apple look on top on BSD UNIX and created Mac OS X which is BSD based. (Actually the project was done at Next, then Apple bought Next.)
Google placed an Android look on top of Linux to make their phone/tablet OS.
NK has made a slightly different mix, a Mac like look over Linux. Linux has an advantage in that it runs on so many different architectures, Intel, ARM, MIPS, S360 and everything else you can think of. Everything from wrist watches to mainframes. I think they picked the best stuff.
