Im not very well versed when it comes to electronics so I dont know if there is already one out there but I think that for both personal as well as business use one thing that I could use greatly is a phone that can project a computer screen like projection where ever you are up from the phone so that you can set it down open up an app such as excel, or powerpoint or things of that nature and insert items whether images or text right from the digital keypad or through voice. I think that this would hands down beat having to carry around a clip board that i stuff papers into and take notes when conducting audits and things of that nature.
