I've expanded on my initial version and didn't double check the lengthy edit with some translation service because I didn't want to miss the edit window.
But I guess the oversight should be clear form context. Can't edit it anyway.
Thanks for pointing out this mistake! :-) (Now I'm going to check this particular word pair more thoroughly next time).
English is not my native tongue but didn't you mean "BeOS, its predecessor" ?
BeOS lived from 1995 to 2001, and Haiku development started in 2001 with a first release in 2009.
