the man from the 1400's buys a computer

One day, I was toying around with my pocket time machine when I accidentally brought someone from the 1400's to our time. Needless to say, he was pretty confused. When I got done explaining what was going on with the technology and such, he demanded I take him back to his time. But first, he wanted to buy a computer. So I brought him to Best Buy.
    "Escuseth me, sir." He began talking to the clerk guy."But I'dth like to trade for one of thine's computers."
    "Macintosh?"
    "No, sire. I'mWilliam, son of Arthur."
    "Good for you. How 'bout a Windows?"
    "My house hath plenty of them."
    "So ya want Macintosh."
    "I've already told thee, I'm William."
    "No,no,no, Macintosh is a type of computer. Just like Windows."
    "Oh, thou couldst have just spoke that. I'll trade for thine's Macintosh."
    "Would you like any programs for that? Word? Paint?"
    "Why wouldst I paint on a computer?"
    "Ya know what? I'm just gonna sell you a Macintosh computer with a basic bundle." And the clerk got a box with a computer inside. The outside had pictures of different  programs and such it could do.
    "Divine."William exclaimed. And he paid for it with a bag of gold coins.(They'd be pretty valuable, considering how old they are.)
    Once we got outside, he took notce of the box."Witchcraft!" he yelled. He then smashed the box(computer inside) and threw it in the dumpster before I could explain."There." he said."The foul smelling beast hast eaten Mackin of toshe's sorcery. I wish to be back in my own time now."
    And that was what happened when I brought a man from the 1400's to our time. Don't ask me what happened when I dropped him off in 2157.
    What's up with the pocket time machine? That's a  story for another post.
