Amazon's next take on the Fire TV Stick looks pretty much the same as before, but it brings along some useful upgrades to keep it current. The biggest difference? It now includes an Alexa-enabled remote at the same $40 price. It also packs in a faster quad-core processor (compared to a dual-core chip before) which Amazon claims is 30 percent faster than its predecessor, as well as speedier 802.11ac WiFi. Mostly, it seems like Amazon is trying to keep the Fire TV Stick more competitive with Roku's excellent $50 streaming stick.
