If you are taking a paperback or two, magazines, plus like to consume tv/movies a tablet might be the way to go if you don't mind reading computer screens vs printed paper.
e-ink looks more like printed paper and has much less eye strain than a tablet. Also, an e-ink reader feels pretty light if you're used to reading paperbacks with one hand.
A tablet would probably have more free/lent book and magazine options. My local libraries offer free lending from Overdrive, Axis360, 3M, Enki, and O'Reilly Safari for books. One offers Zinio for magazines. All of these lenders have free apps or offer open file formats for which free apps exist.
I'm a voracious reader and travel with a phablet (large phone size of 6" tablet) even though I love my e-ink eReaders. Ounce for ounce, a tablet offers more functionality and I'm not packing both.
