At the moment I'm looking at a new developer laptop (though next year is more likely) and you can see that striation already.
I want a QHD display, 16GB RAM (or better) and an SSD, I'm not really fussed about the processor anything i5 or graphics but most machines with my requirements have a monster i7.
Companies seem to think that if you want a 4K you also want Performance. No, seriously I just want this as a glorified text editor. Give me screen resolution, and give me battery life. I'll pay more if you leave out the GPU because then it'll be lighter and draw less power.
Not to mention that a lot of people would be upset at not being able to watch Youtube fullscreen in decent resolution, for which you would need hardware decoding.
Meanwhile both the AMD and nVidia situations have improved with more robust open source drivers appearing. I don't have experience with those to know if they've surpassed the Intel drivers in general quality though.
