We don't know, because they haven't >become popular enough to get publicised. there are many GPLed OSes, but most are written by teenagers or young men with little education or experience. among GPLed OSes with competent designers and implementors, the success rate compared with proprietary OSes is rather good. note that almost all proprietary OSes have educated and experienced designers and implementors. I am thinking also about the abandonment of AmigaOS, OS/2 and (probably) BeOS. it must be frustrating to have written software for one of those once-popular platforms only to see the owner of the platform let it die. I speculate that proprietary OSes need to attract 10s of millions of users or their owners let them die, but that open source OSes can survive for decades with much fewer users. the "fitness landscape" for OSes is quite harsh and severe because of numerous "network effects". "network effect" is a term from economics that every computerist should understand. --upas-vfwrimsfaddulhvxlwqtwrsphv--
