Why you should try using your screen in vertical position, a thread:
First, the terminal looks gorgeous

Source code is usually many lines long but few columns (approx 80) wide so when programming you get a lot of context with little scrolling.
PDFs and other documents usually fit the whole screen. Makes a comfortable reading with little squinting and your neck with good posture (not looking down).
Finally, this is not some kind of absolute truth. If you like portrait mode, keep it! I just recommend *trying* vertical for those who haven't tried and hesitate. I myself cannot go back to landscape, I tried it for a week.
