Also: just do both, because a Kindle is practically weightless and doesn’t take up much space. I’m TOTALLY sold on my Kindle like I never thought I would be, to be honest! I’ve got a paperwhite, and it doesn’t feel so much like a “screen” as I thought it would — also, I mostly keep it in airplane mode unless I’m syncing it, and it often goes for an entire month that way before needing to be charged.
