unobtanium         
Seemingly first used by Jim Getty, a hand-held PC engineer at a large company.
Referred to an ultra-cool product that wasn't on the market yet, but could be applied to any kind of product that is so absolutely cool you fear it will never be available to the common consumer.
Did you see that wireless, flat-panel 20-inch monitor? Hope it's not unobtanium - I want to get one.

In fiction, engineering, and thought experiments, unobtainium is a material ideal for a particular application but impractically hard to get. Unobtainium originally referred to materials that do not exist at all, but more recently, it has been used to describe real materials that are unavailable due to extreme rarity or cost.

Unobtainium

Unobtainium is a term used in fiction, engineering, and common situations for a material ideal for a particular application but impractically hard to get. Unobtainium originally referred to materials that do not exist at all, but can also be used to describe real materials that are unavailable due to extreme rarity or cost. Less commonly, it can mean a device with desirable engineering properties for an application that are exceedingly difficult or impossible to achieve.

The properties of any particular example of unobtainium depend on the intended use. For example, a pulley made of unobtainium might be massless and frictionless. But for a nuclear rocket, unobtainium might have the needed qualities of lightness, strength at high temperatures, and resistance to radiation damage: A combination of all three qualities is impossible with today's materials. The concept of unobtainium is often applied hand-wavingly, flippantly, or humorously.

The word "unobtainium" derives humorously from "unobtainable", with -ium, a suffix for chemical element names. It predates the similar-sounding systematic element names, such as ununennium. An alternate spelling, unobtanium, is sometimes used, perhaps based on the spelling of real elements like titanium and uranium.
