I Will tell you WHY!!!
I am dyslexic. You know what has killed my ability to read on the internet?
10 years of Geocities/GoDaddy flickering flashing dancing text? Nope.
10 years of people not knowing how to use HTML? Nope.
It was the 5 years of the "design" brigade making every website iPhone portrait only compatible. So
Bring back landscape and 4:3 any day!
