Using the Surface as a tablet for drawing has been a huge use-case for visual artists from day 1. Just see this positive review of the original Surface Pro by Gabe from Penny Arcade: https://www.penny-arcade.com/news/post/2013/02/22/the-ms-sur...
Most of those artists ended up buying iPad Pros to replace them with.
This is a weird complaint to me. So what if the display hardware is dated if it is perfectly up to the task it's presented with? Maxing out the specs on a machine for no other reason than to max out the specs seems to me to be nothing but a waist.
And even if it is perfectly suited the the rest of the hardware and any additional RAM/performance would be wasted[1], that's not a good excuse to overcharge for old commodity hardware.
[1] I would be extremely surprised if the rest of the system were designed around the video card. Actually, designed twice, since there are two video card options.
And the video is outdated, period, no air-quotes. There is simply no argument there. Making an excuse for it is nice and all, but it simply is a case of charging a premium for old tech.
