Yeah, I tend to use them except for borders, where I often like them to be specifically very thin, even with larger fonts.

That's not really a big deal in practice, browsers nowadays will scale the whole site, including raster images and pixel sized fonts, as needed the same as percents.

The big benefit of percentages to me though is that they cascade better. If we up the font size of a container element, the child ones will stay proportional to that saving some repetition of sizing. (This applies a bit to responsiveness, but IMO a responsive css that changes font sizes is an antipattern, it means you get unreadable text as you resize your browser (small widths aren't necessary mobile devices!) so better there is to make sure the widths are all fluid.)
