The thread title itself is childish

Linux never wanted to "dominate", but in reality it actually "dominates". Linux is everywhere. In desktop segment its growing fast. More or less every network device(router,modem,switch etc etc) run linux. Most mobile OSs are linux based, linux(and Unix) has the lion's share in server OS segment. And 99% of supercomputers run linux(or its derivatives). This is the FACT.
Unfortunately a lot of people(even techies) can't see this. I am sure they programmed using Turbo-C in their college life and thought its the best compiler.
