This is especially true in UX design.
When I see a website...
- using a ridiculously thin or small font,
- relying on a high-end monitor to provide sufficient color contrast
- loading an unreasonable amount of resources only to provide laggy animations
...I'm wondering if the responsible designer(s) only have 32-in Retina displays and the latest Macbooks to work with. Because on any other combination of devices, the website looks and feels awful.
And I know this because I was formerly guilty of it!
