Sony XTRUD is a new design concept for the future of smartphones in which internal components can be easily changed. It is designed by Francois Rybarczyk and the idea behind this is to think that future smartphones can last well over 2 years by having a replaceable modules. The concept consists of a volume wheel, which doubles as a zoom function for the camera and includes an integrated headphone jack. It also shows the replaceable camera module at back. The owners can easily upgrade camera, memory and RAM modules to increase performance and productivity. It is a great design but needs a lot more work to bring the concept to reality.
