To my surprise, i am enjoying the e books more than the print. I find i can read faster on the screen. I was worried about having to buy the print as well, but i dont need to afterall.
Ebooks are certainly not without merit. You can carry all your CFAI books and your prep notes with you.
However, I do have issues. CFAI books do not have page numbering.
And Schweser notes offer a very skimpy navigation (just the chapters title, no subheading).
