Not to mention all that page flipping in the front alone to find what you are wanting to look at! 4,500 images=a LOT of front index pages! I get antsy just going through 10 of them.

Salon0: That manga I'm familiar with so that makes a common reference point. Did you read those all at a time or scattered? How many at a time? Pre-sized or original format? Data! We need data! (Asking because we have noticed that reading 2 or 3 at a time with a break between sessions seems to actually extend the battery time immensely. Slow period at the club, no recharge needed that week. Busy, charge every couple days.)

We might be in a weird usage spot here since our readers are used for books (big Baen fan here) and the local manga club so we're getting a heavy mix of text and graphics but our units are sequential so if there was a line flaw we would never know.
