If I purchase a roku TV for use in my home, will I be able to access the Xfinity app and watch everything I can on the computer or would I have to purchase another cable box?
The Roku app will supposedly work alot like a full cable box. It will require a reliable Comcast Internet connection. It is currently free, but may have a monthly fee when it finishes Beta testing. Best guess is a full box fee ($9.99) minus a device fee ($1.50), for a total of $7.49/month.
