 I just call my Apex a note taker.  That can include any kind, electronic or not.

Subject: Re: [nfb-talk] Guide Bots

We dog users get that too.  I've had my dog called a Seeing Eye Dog(which she is not), a helper dog, and even a blind dog.  Unless I have to talk to the person extensively, I let it go.

My mom still calls my Braille note a Pacmate, which might annoy Humanware, but personally, I think it's funny.  And as long as my cane isn't called a wand anymore, I think I can live with anything else.
If it's someone you know well, then just correct them quickly and gently.  Perhaps we should put print labels on all our products to help them out...

I think a guide bot would be interesting...  But I don't want a machine to know where I'm going.  If it could be programmed just to follow my duirections and lead me around obstacles like a dog does, I think it would be ok.  But I do enjoy working with a dog.  I think an animal would make a better partner than a machine.  :)
