Kindle?

I've been thinking about getting a Kindle. The main thing I would do with it is read articles in PDF format which I would download from JSTOR and journal websites. I heard that Kindles are better abou this sort of thing than what they used to be, but I thought I would check in with the Smokers to be sure. Are Kindles indeed better about this sort of thing than what they used to be? Many thanks.
