We need something to get streaming TV services (NowTV, Netflix, Amazon, and one other I forget) onto the TV, and the Roku boxes look to be a good mix of ease of use and features.
I am befuddled by their range however - they all seem to do what we need (private listening could be nice but isn't essential). Have you noticed a difference among those you've used - some are sluggish?
I've missed the Black Friday deals but hopefully more cut prices soon
