E-reader Advice

So I’m finally going to get an e-reader!

 
But there are a lot of choices and I’d love some advice.
Which ones do you have? What do you love about them, hate about them? I’m leaning toward the Kindle…but am open to any suggestions.
Also…there’s still time to enter my giveaway so you can win an ARC of In the After. Just click on the giveaway tab!
