This is clearly an extreme case, and quite impressive. I was commenting on the general case of developing on a phone screen. 2300x1080 phone screens are now on ~200$ phones, while getting more than 1920x1080 on a 14'' laptop is difficult and gets you a "why would you even want more than FHD on a 14'' laptop" comment consistently. At least 16:10 is now becoming more common so 1920x1200 is growing a bit.
