In terms of resolution and size, I think the iPad and the Google Tablet have the greatest resolution and make it easiest to read. The big e-ink reader from Amazon (no longer for sale, I think) is easiest on the eyes because it’s the closest thing to paper.
But honestly, look at your past study habits and see how you learn best. If you like to highlight or write yourself notes in the margins, hard copy is the best way to go.
I ordered the e-book when studying for Level 1 and regretted it. Printing PDFs from the VitalSource is a pain. The files are huge and the resolution is very poor.
