If you can, could you look at the touchscreen chapter
and see if there is a match?

I looked at the 6 pages of the 2nd edition (1997) on Touch Screens found in Chapter 52 and sent the results to PJ. ISBN 0444818626 hard back edition, scanned by Google I think, looks like the one found in Google Books, which unfortunately omits several of the relevant pages (1317 through 3122). From the index you display, it looks like no more content is in the original edition.

You could note one paragraph actual demonstrates a couple of issues at odds between Apple and Microsoft 20 years later:

Touch screens have several disadvantages. Because the output surface is also the input medium, parallax effects are introduced. Also, the user must sit within arm's reach of the display. These characteristics of touch screens may constrain both workplace design and operator mobility. The need to repeatedly lift a hand to the display may also produce arm fatigue. Additionally, the user's finger or arm may block the screen. Another disadvantage is that the size of the user's finger tends to limit target resolution. The takeoff touch entry strategy or a stylus can be used to address this problem, but the pointing gesture then becomes somewhat less natural.
You could probably dig around and find all sorts of 'issues' the two parties have publicly claimed to have 'discovered' by sweat of the brow (and deserving of patent protection as a result).
