I doubt there will be a big enough market for this. Most who need those type of keyboards are cord cutters who need a simple keyoard to watch tv. They dont want anything too large nor too expensive. The best one at this time is a cheapee from logitech. Your best bet for information would be from the different gaming forums out there.
Hi my name is Anthony and I have been converting gaming keyboards into lap or living room keyboards for the past 3 years. It all started when I got tired of PC gaming on a desk because I was sitting at one for eight hours for work. So I conjured up this idea and starting slapping mouse pads on keyboards like the razer death stalker essential and the steelseries apex raw gaming keyboards. It worked out well and I was gaming on my couch and never went back to PC gaming on a desk agin. If you guys are curios how I started making living room keyboards I have a couple of videos on youtube that guide you threw the process. www.youtube.com/channel/UC5GQp_7vhdTN8zRNFXu7eYQ.
So my question is do you think there is a place for the up and coming living room keyboards like the roccat sova or the razer forge systems. I personally think so being that I have been doing it now for the past 3 years and love it. Give me your feedback on how you feel this market will do in 2016.
