FPGAs are incredibly closed, outside of Lattice Semiconductor's tiny FPGAs (unsuitable for computers). In all practicality for "openness", any open-source advocate should rather use Intel/AMD than Xilinx/Altera.
Closed-source synthesizers, closed source bootup, closed source loaders, etc. etc. You're pretty much trusting the FPGA software more than any CPU.
Fpgas are very unsuitable general purpose computers. De10 nano is a very beefy fpga and can barely play doom acting like a general purpose 486 and lacks a fpga
Oh well, I figured that a PowerPC Notebook was for hobbyists.
What I would find fascinating is to think about languages and OSs for FPGA and try to break loose from the utterly boring C/Unix/68k,x86,MIPS,blah paradigm. Having something turnkey with attachment to various ports and a display would be kind of cool. Maybe that exists already.
I worked on a project with a processor-on-an-FPGA and while it wasn't fast, the video codec in FPGA made it useful. Kind of a neat thing I think.
Ppc notebook is a thing because ppc has been “open sourced” so you can just make ppc chips using great documentation with nobody knocking on your door. As a technology it’s dead as a door nail but it’s free as speech.
