Wow you're a fast reader!
Indeed, in a perfect or wannabe-perfect world that is were we're heading.
Unfortunately it's not our world's case... Technically Linux is superior that's why it survived and that's why it moved from a niche phenomen to mainstream. But... there's a lot of money that think Linux shouldn't succeed. The sad part is that those money, instead of moving into improving their own technology to become techically superior, are moving into killing it from rather different areas: deceiveful adds (like the ones we see all over the net these day with Linux costs more money than windows & co. which is rather hillarious, since price is the last argument, other more important come in mind when one thinks of Linux. Funny I never saw - yet - ads that say windows is technically a better choice

), into enforcing patents which in turn would kill every bit of free software since, beeing free, it will not be able to pay for patent fees, etc. etc.
Bottom line: Linux is getting stronger, but the competition is getting tougher and tougher, and not last dirtier... and the dirt definitely does not come from Linux. Let's hope this wonder baby of IT has gathered enough strenght for what is to come...
