My grandfather owned a shoe store in a small town. He had all sorts of tools used to stretching shoes, making a dimples for corns and some others that quite frankly looked like some sort of medieval torture device. That I know of, after the store closed, they disappeared. *sigh* They remind me of my grandparents, I miss seeing them, the tools and my grandparents. Perhaps they are still used in shoe repair stores and mom & pop shoe stores.

You forgot all above iterations plus the blu-ray versions.

I HAVE SEEN plenty of uses for this. I did IT at a small news paper and when I first started, we had 3 or 4 Ruby iMacs acting in server roles. They were finally replaced with MacMini's. However, these did not require OSX Server for their purpose, but for tasks such as moving wire streams, file conversions, getting files to and from the image adjustment servers, etc. they really were perfect for the task. For instance, we setup an old dual G5 for a file server role for dropping articles with OSX Server...if and when that system dies, the need for a rack-mount server or MacPro is over-kill for 80 or so users, MacMini however...perfect. There are many light duty server roles like this that a Mini running OSX Server would be useful and cost effective.

Sure, id doesn't add much to the cost, however, when was the last time you saw any publicly traded company not be as cheap as possible? Even if it only costs about $10 to $100 to make the vehicle E85 compatible, they are not about to absorb that cost over thousands of vehicles. Hell, what would it have cost for Sony to keep an IR port on the PS3? 10 cents? As it is now, you must use either a controller or the Sony bluetooth remote (granted Logitech as an adapter out now for $60, substantially more than a .10 IR port) How much more did it cost for them to have a fully backwards compatible PS3? An extra $1? How about an HDMI chipset that could bit-stream audio? An extra $1? Do you really think car companies are any different?
