Yes Roku does have youtube but it is clunky as hell. I think it is better to run an HDMI cable from your computer to your HDMI capable tv and watch youtube that way.
Also I prefer the wired Roku over wireless Roku.
I plan on running an ethernet cable to the Roku box. I have wireless but I prefer not to use it if given the choice.
