Those touchscreen phones with multi-touch technologies are pretty cool but it seems that future belongs to the holographic phones.
Here you can see a conceptual design that is based on holographic display technology. This phone is designed for Apple by Josselin Zaigouche but, sadly, it shouldn’t come to the market before 2020.
If you look better, you would see why this thing cannot be produced now. This is still something that can be seen in sci-fi movies but we believe that nothing is impossible and one day such phones and devices could become reality.
