I think all A-Eon are selling are rose-tinted Amiga glasses, nothing more; it's like beer goggle surgery for nerds and the number of people seduced by this hype has amazed me.
What never ceases to amaze me is that people will actually prefer software and hardware NOT to be used.
What do we lose if this particular computer gets sold with OS4 ?
Nothing. But it'll be fun to play with.
