content: Everyone is right now. Go to any computer OEM webpage and search products. You don't need 20 (!) different models of laptop, each with varying screen sizes and specs. 11 inch, 13 inch, 15 inch, 17 inch, each with a low spec, mid spec, high spec, all with or without touch, done. Design them to be as similar and to share as many parts as possible, DONE. Now  you have 1 mostly identical model, with mostly identical hardware parts (sound chips, wifi, etc.)  Driver support is then a ton easier, and repair is a ton easier as the parts are mostly compatible across models. You avoid things like this: I have an environment with Yoga 900's. The gen 1 is perfectly ok to work with, but the gen 2 has a very strange disk controller that makes even applying a simple image a pain in the ass. The gen 1 controller was, and still is available, future models use it, but for some reason they went with that bastard disk controller on that one model only.
