I know there are many reviews for this out there already but whats one more :)
I recently picked up a Google Chromecast from Amazon. See the link below.
I believe I paid $35 for it. If you don't know what the Chromecast is, it is a small device that you can plug into an HDMI port on a TV and then "cast" content to it from various pc apps as well as phone or tablet screens.
Personally I use this device to watch movies from a Plex Media server as well as Youtube play lists.
I have used this on vacation to watch content from my tablet as well.
For the price this can't be beat. Pick on up from the link above.
