I have to be honest here; I don't particularly understand the hype of this ultra-mini, ultra-trendy e-reader.

I prefer my basic Kindle, which is already small enough to fit in my purse.

It also doesn't have backlighting, which means you can only read in bright settings (a personal dealbreaker for me).

But surely there must be a reason this thing is popular.

With a 3.7-inch screen, it's not only small enough to slip into your pocket (yes, even women's pockets), but it also magnetically attaches to the back of your phone for seamless reading on the go.
