You said -- "... but this thing is just too big."
Now, that's hilarious. You know..., if they wanted to, they could make something so small that you would have to use the head of a pin to punch in numbers and use a magnifying glass to read what it said. It would be pretty small. I imagine it wouldn't be too hard to make it as small as a ring.
BUT, here the ridiculousness of that statement. Getting stuff so small that it's no longer suited for *human consumption* is stupid. You have to see it, You have to be able to "handle" it. You have to have some kind of "interaction" with the product. That *requires* -- some *size* to make it happen.
"Big" is necessary for "functionality" for human beings. If you are a computer, on the other hand, and only interact through electrical signals, then you don't have to concerned and can make it as small as you want.
So, no, it's not too big. People are that big, which requires it to match up with "people".
Did I really have to explain that to someone -- apparently so...
