Well let me explain everythnig first and please read the whole thing before answering.
I know this is alot of info but,
See my one roomate is a big T.V. watcher and he is willing to try Roku. He has a Roku 2 and a Roku SE. We are in the process of buying a house and they do not have Comcast or Centurylink Prism.
I have another roomate who is like me who does not watch much if any tv and he is a big downloader.
If he is downloading on the slow 6Mbps internet that the Roku would be running on would make T.V. watching unenjoyable for the T.V. roomate.
So if I got Directtv because the T.V. watching roomate like sports and local channels and live sporting events after a year with direct we would be paying roughly 290 a month for home phone, 2 dsl lines and tv, we already pay 12 for Hulu, 10 for wwe, and 5 for acorn tv. If we went with just Roku we would get 3 DSL lines and Hulu, WWE, acorn tv and Sling T.V. and a home phone and over 2 years save 1000 dollars.
