The original "gorilla arm" UX research is much older. However, Microsoft surface was something of a niche hit, and spawned a number of clones. PC laptops with touchscreens are quite prevalent even if they're not in the full-hinge form factor. They work a lot better if you can lay the screen flat or at a low angle in your lap.
Re: the stylus sub-thread, I've actually used cheap Android resistive+stylus phones and a Compaq Palm Pilot clone and .. yes, they were really bad compared to modern phone interfaces. The stylus has a niche market for artists, who need a high quality pressure sensitive version.
(edit: attempting to find the original citation for "gorilla arm" takes me to the Jargon File and the early 1980s. Along the way I found the delightful existence of a UX researcher with the name Sebastian Boring, though)
I've used two touchscreen laptops during the Windows 7 era, and I'd largely agree with Jobs. It's great for some niche cases, but sits unused 99% of the time. Of course that was before Windows 8 completely redesigned the UI to better support touch, but that also hasn't lead to an appreciable portion of Windows laptops selling with touchscreens.
The Surface devices are a bit of an exception. For the tablets it works great. The convertibles that were a laptop with a screen that can turn into a tablet (or just be attached in reverse, so you have a very heavy but powerful tablet) were also great presentation laptops. Though apparently that niche was too small to support the exotic hardware. I don't quite get the appeal of the current surface laptops. But the ones I see in the wild are almost all the tablet surface devices.
