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.

With my left hand, I poke the required bits of my corporate training modules. With my right hand, I rest my fingers behind the right side of my display and quickly click the "next" button. I get through training in record time.
This is the only time I use the touchscreen on my (non-convertible) laptop. It seems like touchscreen is most useful when you have big enough targets spread out over the page. Most software I use isn't designed like that. Aiming for the restore button may result in hitting the close button...

To be fair, the point at which Microsoft rewrote their UI to be touch-friendly was Windows 8, inspired by Windows Phone (RIP).
