having started off with a Widelux swing lens that gave me 140
degrees, and a Fuji X-1 that didn't even give that. I just like
wide angle coverage, and stitching two or three shots to get a
reasonable horizontal coverage would be fine with me.

view stereo prints or screen shots. But NOTHING can beat a film
transparency... which is why I usually shoot with two cameras on a
hand-held bar. Both have matching 35mm lenses, which is about ideal
for good stereo effect. I've never thought of stitching them, though.
Must try that one day...
Incidentally, over/under viewers work well with panorama prints. You
just have to "scan" by sliding the print(s) through the field of
view. Sort of manual VR. <grin>
