I'm less than half Betty's age, and I have many of the same problems, both on mobile web and on my laptop (which has a touchpad that does gestures and multi-touch).
Zooming/resizing, in particular, pretty much just happens at random for me. I can't avoid it when I don't want to resize and can't make it work when I do want to resize. I didn't love the old "+|-" UI elements in the old Android (way back in the ~1.3 days, I guess), but I didn't hate them, the way I rage about random resizing. And, it's universal, too. It's not a thing that is unique to Android, or iOS or Windows, or Linux; I have these problems no matter what OS I'm using. Multitouch interfaces are really difficult for me to use.
My mom has an iPad, and she has a hard time with this kind of stuff, too. But, then again, the mouse was also hard for her...she managed to almost entirely miss the desktop/laptop computer age, by leaving my dad in charge of all computer-oriented activity, but now that he's gone, she has had to learn.
Anyway, it's clear that most technology is designed by and for able-bodied people in their 20s and 30s. Everybody else just kinda has to figure out workarounds (my dad used to have the resolution on his display set really low in Windows, so that everything would be big, so he could read it...there are ways to make Windows use large fonts and such, but not all software respects those settings, so he found the most universally consistent way to get big fonts was to work at a very low resolution).
