Re: It's a typical marketing decision
"Companies see that 2 "Full-HD" monitors next to each other are popular, therefore they bring out one that combines the same number of pixels."
Yep. The primary bit of software that our section of the company relies on 90% of the time was always a pain on the 4:3 screens because they put the main menu in a column down the left side so we were forever scrolling right. They finally fixed that issue about a year after widescreen monitors were standard issue and put all the menus along the top. Now we are forever scrolling down. Twats!
