It gets pretty tedious, when you are doing this for 80% of the sites you are visiting.
Also on slower hardware - zooming is a drag, and it can be slow.
The browsers do allow for customisaton, and I think this is probably the easiest thing for an end user. I use a minimal font size of 16px, and that works for me. But it does break some sites - Facebook's layout has been broken over the last month like this for example. Which is fine if you kind of understand the reason for it, but could confuse other users. Just as some navigation breaks, think of horizontal nav, that falls onto another line when the text size increases - I'm thinking hover states, and drop down menus.
