I also am an avid fan of Kodi... And although people are telling you that you have to install it on specific hardware... They are wrong.. You can install Kodi on just about anything.
I have successfully installed it on: IOS & Mac (provided they are jailbroken), as well as any instance of Android (without rooting), and even repurposed an older laptop and using it as a "media centre".
The issue with Plex.. Or I should say where plex Plex is lacking is that you need to add channels to get the same level of service, which are available. At a premium. An example of this is hockeystreams.net. At the end of the day, Plex gets you to media you own or want to pay for.
I purchased this:
http://www.amazon.com/Mk903v-Google-Don ... roid+stickand got a small bluetooth handheld keyboard and trackpad for my bedroom.. I've also got "AC" wireless (NotHawthorny I really recommend investing in this if you want to go wireless with decent speeds, otherwise you're bang on about a hardwire connection).
within 10 minutes I had Kodi installed, TVaddons.org & super repo added. Within 15 minutes I had the 2015 ICC World Cup in HD. I was watching all televised hockey games, regardless of blackouts.
Now in regards to trashing your cable bill..:
1. This isn't going to be easy as clicking on a channel and it working... Lots of channels do not work properly, or at all
2. You are going to need to have some technical prowess or at least aren't worried about doing a few google searches and applying the solution to your issue
3. You're going to spend more time browsing the selection, and less time watching it.
4. You can find local news channels, but its not like just putting on CP24 and leaving it on.
If you get stuck on anything, please feel free to ask me as well, I've been using XBMC, back when it was released on the XBOX, and it definitely has come a LONG way... But I will say there isn't any other software/service that can hold a candle to it.
