Though the YouTube Channel doesn’t officially exist on the Roku yet it is expected to come any month now and there are still ways to access YouTube from the Roku even without the official channel such as by using the VideoBuzz channel which has access to YouTube.
The Roku 3 has a free iOS and Android app that lets you use any Android or iOS device as both the remote and a channel surfing/adding vehicle so you can make sure you pick the over 750+ channels you want to add.
The dual band wireless promises faster wireless speeds and further range, which should greatly help those who had slower wi-fi connections to older Roku models.
I have been using both the video channels in my blu-ray player, Samsung Smart TV, Xbox 360 and Wii U but nothing compares to the Roku in my opinion as the video streaming device of choice. I have 3 of them in my house a Roku XDS, Roku 2 XS and I am really considering getting the Roku 3 to replace the Roku 2 XS in the bedroom because the headphone jack makes it great for one partner to watch some TV while the other falls asleep.
