    dollars per ounce per calculation

    Would you please explain the following in red more easily?

    To see this same pattern unfold in technology, let's examine the Osborne Executive Portable, a bleeding edge computer released in 1982. This bad boy weighed in at about 28 pounds and cost a little over $2,500. Now compare this to the first iPhone, released in 2007, which weighed 1/100th as much, at 1/10th of the cost, while sporting 150 times the processing speed and more than 100,000 times the memory. Putting aside the universe of software applications and wireless connectivity that puts the iPhone light-years ahead of early personal computers, if you were to simply measure the difference in terms of "dollars per ounce per calculation," the iPhone has 150,000 times more price performance than Osborne's Executive.

    Thank you.

    Re: dollars per ounce per calculation

    It's a little awkward. The point is that the computers today are not only lighter, but faster and cheaper.

    If you consider how much weight (ounces) a computer needed for each calculation it was capable of performing, then you could have an "ounce per calculation" figure.

    If you then figure how many dollars you paid per ounce, you could then figure out how many dollars you paid per ounce per calculation.

    Re: dollars per ounce per calculation

    Thank you for the answer.

    I don't know much about computers.
    I understand your explanation literally, but it's confusing.
    Was the weight of a computer important for calculation (in the past)?
    Do the dollars you paid per ounce refer to the money you paid when you bought the computer?
    Is this explaining how the price of a computer was set?

    Re: dollars per ounce per calculation

    No, it's just making the point that the weight is a lot less now for a lot more computing power.

    Computers have never been priced by the pound.
