If you already have and use Prime, and want to be able to watch Prime (and non-Prime, rented/purchased media) on your TV, it's a relatively cheap way to do so (especially at the discounted $19). Plus it offers a bunch of other services into the bundle (Netflix, Hulu etc.). If you already have and use a Chromecast, not much use really except for Amazon content, which doesn't work with Chromecast (presently, at least; no idea if they plan to make it work or not, they may wish to restrict their services to their own hardware). If you currently have neither, Fire Stick might be a bit cheaper (with the Prime deal; non-Prime users can apparently take out a free trial and get the reduced price too), has a remote instead of relying on another device (phone/tablet/PC) like Chromecast does, supports different services (most notably Amazon's own service for Fire, HBO Go for Chromecast), has an actual interface and on-device apps, rather than again relying on external devices for these. Of course, if you have a Chromecast on your TV(s) already, none of these are probably enticing reasons.
