Yes, Mongo is trolling. Either that, or he cannot see past his own nose.
The fact that it wouldn't be for everyone, doesnt mean that it wouldn't be for anyone. The debate on whether emulation is worthwhile or not has been long hashed out and decided. This would be the most realistic emulation anyone could hope for. Using it as a standard PC would be buying as a functional piece of art.
What sane person buys an expensive custom made PC to emulate a $10 C64?
Is that worthwhile? Who decided that?
Is the PC emulating the $10 C64 more realistic than the $10 C64?
The lack of a proper keyboard makes this anything but functional as a PC.
The reason "Nobody missed any keys back in the C64's heydays" is because they were running software that was designed to run on a computer with the C64's keyboard, and the claim that "Most of the missing keys are unused by most people anyway" is completely absurd.
Tab key? Alt key? Esc key? More than 4 function keys? Separate cursor keys? Don't need those. Who uses those anyway?
Doesn't really matter though, because all Commodore USA has the ability to manufacture is bullshit.
