Samsung Galaxy S4 Concept Pictures and Video

There have been many people speculating about what the newest Galaxy device from Samsung will look and feel like. It is said to have the name “Galaxy S IV” or Galaxy S4. Recently, some people have decided to make concept designs of the device and also throw in some features they would like to see. The video below is even predicting the next Android version of 5.0 Key Lime Pie. Many images point towards the idea of completely removing any bezel and having an edge to edge display. What does everyone think of this? I know it looks amazing, but is it practical?

There is also the idea of a laser keyboard that would be fantastic. Personally, I think that this feature is just a concept and will not be included with the Galaxy S 4. Hopefully I am wrong though!
Take a look at the images and video below and let me know what you think!
