The majority of people are still using 1080p screens these days. My laptop has a 1440p screen but the other monitors I use at work are 1080p and work fine. I don't think anyone will be disappointed by a 1080p screen.

Right, but for how long? It would be much easier to upgrade a separate monitor down the road. Otherwise, the Pi-Top team would need to make duplicate products: one laptop that supported a 1080p screen and another laptop that supported a 4K screen.
