The Problem:
Apparently, many websites will have difficulty adjusting to the new retina display laptops, popularized by Apple. The sites simply won’t look right on the screen.
The Business
Updating websites to comply with the new specs put forth by the new screens.
Doableness
In most instances, you are simply updating or changing images. Sometimes, the changes will need to go deeper to handle the changes.
My Thoughts
If you could find a way to automate the fix, life would be a lot better. That said, there’s money to be made either way.
