And I find I remember next to nothing I read in digital books, even eink books, whereas I can constantly recall stuff from physical books I've read. Plus, the act of phyiscally reading it does something, and I can generally remember roughly where I found something without need for a search.

Physical books just for me are a no brainer when I can get them. They're orders of magnitude better than anything digital for research, even if it isn't as 'efficient' and time gets 'wasted' (I'd also put forth an argument it isn't necessarily wasted).
