Good to know

This term Vaporware popped up when i was reading about SlingCatcher.

"Vaporware is a somewhat derogatory term used to describe a software or hardware product that is announced by a developer well in advance of release, but which then fails to emerge after having well exceeded the period of development time that was initially claimed or would normally be expected for the development cycle of a similar software/hardware product. The term implies unwarranted optimism, an as yet unannounced abandonment of a project, or sometimes even deception; that is, it may imply that the announcer knows that product development is in too early a stage to support responsible statements about its completion date, feature set, or even feasibility. However, most vaporware would not be considered a hoax since the makers have a genuine intention to create their product, even if it ultimately never materializes. Products with unspecified release dates or long development times that outwardly demonstrate regular, verifiable progress in production are not normally labelled vaporware."
