Our entertainment systems are quickly becoming packaged into smaller units, just like our cell phones were quick to become smartphone, with picture taking abilities and more.  We’re smart about what type of gadgets we carry around with us and we know what devices would work well with each other and which would not.  Imagine if our cell phones also came with a travel sized fork for us to dine with.  Would that really be useful?  No.  But if our cell phone could control something the same way a TV remote does, well then that is technology put to good use. Home theater systems can range from compact to large, but newer entertainment units that stream digital media, come in a size that can be held in the hand.  These mini receivers are not there to plug peripheral units into; they are there to receive information wirelessly.  The Roku and other units like it are capable of replacing the modern cable TV system by streaming video from the web straight to a monitor.  The beauty of this system is that it can be controlled with a remote and can also be wired to your personal computer.  Imagine being able to access your Serato playlists using your remote on your television. http://www.audioholics.com/reviews/digital-media-servers/roku-3-streaming-player-4200r
