Vaporware
Vaporware is software that was announced by a developer, but never made it to a real product.
It is constructed of vapor, floating in space, but never materializes; hence the name vaporware. It always has the best features of all programs currently on the market. The only problem is that you can not buy (or do anything else with) this software. In fact it exists only in the minds of the developers.
Vaporware is sometimes announced by companies in order to damage the development of real products by competitors; if the customer believes the hype, they may put off purchasing the real product to wait for its vaporous rival to mature.
In rare cases vaporware may actually materialize after a long waiting time, often several years. Vaporware may be hyped.
Vaporware is also a company selling Amiga Internet applications.
