This isn't the first time we've seen a dual screen tablet. But something is unique about this double display device. The screens are actually on the outside instead of folding together like the Sony Tablet P. This tablet is still in the concept phase so there's not a lot to tell. Will it be useful? I believe this type of folding tablet will be more convenient to use as the screens are readily available. There's already concept phones that have wrap around screens, so why not tablets.
What we can tell is the NEC table is an Android device and from the looks of it, it will also have calling features. Will it be a phone or tablet or another phablet. We will keep you guys posted so stay tuned.
