It's not so much an Arduino as a small embedded processor be it a PIC, ATMEL, TI, etc...
We've become spoiled by our telephones. My iPhone has more storage, memory and I believe runs faster than the AMDAHL 470 computer I used in University. Yet that AMDAHL supported over 350 users on terminals. My first exposure to Unix was PDP-11 with 64K words of memory. Nowhere near what I have on my BeagleBone Black but the BeagleBone does run a version of LinuxCNC although I have yet to try it on the JGRO router. But note that EMC has to run a particular real time variant of Linux in order to do the CNC. That writing code on a Linux based system to create a pulse stream to run GE-35 Christmas Lights is pretty well impossible without the real time Linux and then the programmer needs in depth knowledge of the OS. Contrast that to any of the small 8 or 16 bit processor and the project is dirt simple.
