I attended my ADN program before ebooks were a thing (and I had to walk in waist deep snow a mile uphill both ways... sorry, I couldn't resist!)
I agree with Shanimal though, it really is about preference.
I love ebooks for pleasure reading -- actually it's thanks to Audible I have time for pleasure reading! But for in-depth study I like to have a book I can write in and dog-ear. My 15 yr old daughter is a heavy tech user as most teenagers are; her school books are all on her school-issued iPad. However for AP US history, she HAS to read her heavy reading assignments from the physical textbook. She says it's easier than reading off a screen.
For stuff like pharmacology, I tend to utilize the tools my hospital has (Lexicomp and Micromedex), or I will ask the pharmacist. I haven't used a Mosby's type drug book since nursing school
in the early 2000s.
Occasionally I will Google something. One example: Le Fort fractures. I had never heard the term until I had a pt with a type III. So obviously wanting to know what part of his face was broken, I Googled it.
How I could see ebooks being a good option is if lugging a bunch of those huge tomes is too difficult.
