Ahh, AutoCAD...the desktop app that pretty much _ruined_ me for all future applications.  The first application that I ever used to actually create something new, before I even really learned to write code.<p>The beauty of AutoCAD was that it was designed for power users only.  The learning curve was almost vertical...but to me, that&#x27;s the true sign of a powerful application.  Fortunately, I had a high-school drafting class and then took a class at my local community college...having a real-life instructor was invaluable.  It was exclusively designed around a &quot;one hand on keyboard, one hand on mouse&quot; stance, but you could do _everything_ from that position.<p>Once I got over the the initial learning hump and most of the commands became second nature, I could work almost as fast as I could think.  I was working on something like a 500Mhz PIII running Win98, and I cannot remember it ever lagging or crashing while I was working.<p>But the most important thing to me?  Since it was a desktop app, it had 100% control over the keyboard and mouse inputs.<p><pre><code>  No accidentally closing a tab or refreshing the page.  
  No browser updates f&#x27;ing with my right click menu.  
  No scroll-jacking.  
  No zoom-jacking.  
  No shortcut-key overlap with plugins (looking at you, 1Password&#x2F;google docs)
  No input lag...EVER.

I miss that level of user&#x2F;machine interface...Every. Single. Day.
