True. I could use a null modem cable too, I have done just that in the past. I could also use my PCMCIA 10baseT card too, I've done that in the past too. Given the choice however I like nice tidy solutions that fit inside the case.
Please understand that I'm not preaching, other people will prefer other solutions but for me this one is preferable and let's face it that's the whole point, to have a choice. Our choice to use Amigas is not logical to some people but it is our choice.
