The actual issue is not so much that it looks like a hoax, but that it is so endlessly poorly carried out.
I would tend to agree. But the original C64 was poorly carried out, too, so this as a nostalgia product has some merit.
Now, before people roll out of the shag carpeting to rage at me, the C64 was an inexpensive and well marketed, but technically second rate product. I mean, they put a whole second 6502-type processor in the disk drive and set the machine up to read/write from the disk over a pokey-doke serial interface. That was never impressive. Adding a Hard Disk to your C64 system amounted to again buying a whole separate subsystem significantly more expensive than the C64 itself that, again, was a whole separate system with another processor, that talked to your C64 over.... get this... a pokey-doke serial interface.
Not impressive, except in a marketing sense. The C64 was a marketing phenomena, and as a result many youngsters 'cut their teeth' on it. Then, said youngsters went on to make good use of their C64 in spite of what was built into the system, basically doing an end-run around the way it was set up.
