Nowadays laptop computer screens, even the ones intended for use in the office, are coming in widescreen. I think it would be useful if these screens could be tilted vertically like for editing text documents.
Widescreens come at a ratio of 16:9=1.77. A standard letter page is in a ratio of 11:8.5=1.29 so the length of a letter would fit nicely if put at the width of a page. Anyway, it's an idea.
Reward: just knowing that took the time thinking of me to look for something is enough
