The only issue I saw was that it wasn't positioned properly
From what I've seen in the new Web is tv platform is there there are key features that can be used to help this out .One issue was that. Web os didn't scale up well to tablet size
But if it can be built into 4k tvs it's definitely not a challenge.
I'd love to see entertainment oriented tablets in the market place
Running a variation of the web os tv ui if it's "ten foot ui" can be turned into
15"inch. [viewing distance of course ] user interphase it would be perfect
Also with webos tv's quirky little mouse pointer. My suggestion if it where ported over is to not get rid of it
I feel that tablets and tablet computers don't augment the intelligence of the mouse to follow the finger and it forces users to use Bluetooth mouse pointers or trackpads . Combining the mouse with dragging and long press menu eat the ux level like how it is done on the tv is a perfect solution .
