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).
Websites mostly scroll vertically
Most scrollable lists on the internet are vertically oriented.
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.
