&gt; So we finally have a free choice of OS<p>Not really, you still a browser that implement all this stuff. The only difference is Open tech vs proprietary.<p>Open technologies are obviously a good thing. Writing a software as complex as Photoshop for instance with the exact same features with HTML&#x2F;CSS and JavaScript isn&#x27;t going to fly and be usable for someone who has to work 10 hours a day on it. The performance issues will be significant. It&#x27;s not a big deal for an text editor though I still can&#x27;t open a 5mb log file in Atom for some reasons. No problem with Sublime Text 2 or Vim. Why is this ?<p>My point is Web techs aren&#x27;t a silver bullet.
