You joined today to say that the Apple design team is atrocious because they didn't put rounded corners on the LCD? Are there any other laptops on the market with rounded corners? What benefit would it serve?
It doesn't make much sense to have rounded corners on a Mac display. For anyone who chooses to hide the menu bar or Dock and use those corners for application windows it's going to look terrible. Same goes for fullscreen mode in some apps. And the cursor is going to disappear every time it goes in the corner?
