Make sure to press him to see prototypes, parts, or anything else that might show all he has is a website and one hastily assembled pc in a c64 shell.
If they don't even have prototypes of these amiga pc's already assembled, then its for sure a sham.
Ask to see workbench 5 also. If he can't show you anything then they haven't even started on it yet.
I just think they keep announcing and then cancelling products. There is a reason for that (they don't have any)
