I am now using Roku Express+. It has been activated and working great. No complaints.
My question :
If I buy a Roku Ultra, do I need to go through the process of activating Roku Ultra or do I just connect it to my TV and it is good to go ?
While I am here, may I ask a slightly off topic question ?
What is the difference between Roku and Android TV Box ? Such as....... what can one do that the other one cannot ?
You can use the same account.. if you sign up with a new account, you'll have to pick your channels all over again. Some people sign up for a second account if the primary user of the new device is a different person, but most people just have one Roku account.
