Roku 3 ,Apple Tv Whats the difference?
I want more TV with out cable
The Roku is mainly used for streaming video, and anything that has streaming video through a website or a smartphone app will probably have a channel on Roku. For those that haven't invested in the iOS or iTunes ecosystem, it's really the best deal in media. While it can be used to DLNA and Miracast, configuring either to work properly with the box is a pain.
The AppleTV has some streaming functionality of the Roku Box, but not nearly as many channels. It makes up for this, however, in connectivity with Macintosh computers (Airplay), iDevices (Airplay and functionality), and it's access to iTunes (streaming content from iTunes on your computer and access to iTunes Music, Movies, TV shows, Podcasts, and other media). AppleTV is also the way to go when it comes to a household with an existing base of iOS devices (iPad, iPhone, iPod Touch) or those with an extensive collection of media in iTunes.
Another option is Amazon FireTV. It's similar to, but more powerful than Roku, though it's also limited on channels it can access. It makes up for this with it's unprecedented access to Amazon Streaming Music and Video, including Prime.
Another option is to get a smart TV or a smart Blu-Ray player. Either device will give you plenty of streaming options.
