Sony's Playstation 4 does most of the TV-watching things a streaming TV-watching box is meant to do, apart from the fact that watching Netflix using two analogue sticks is a pain. Sony's new Bluetooth universal remote should fix all that.
The new PS4 Universal Media Remote, $US30 from your favourite (US-, UK- or Canada-based) internet retailer later this month, should make the PS4 a little more palatable to your spouse. Rather than having a useless $400 box that only plays video games with a controller thingy, you now have a $US400 that controls the PS4, apps like Netflix, and any other IR-controllable things around (like the TV itself).
So, in theory, you can replace all your remotes with Sony's decently-cheap Bluetooth option, and live a happy streaming existence thereafter. It still probably won't beat dedicated remotes like Logitech's Bluetooth-enabled Harmony, though.
