We found this interesting patent application for a PDA that can also function as a cell phone. Yes, there are numerous smartphones out there. No, this patent application isn’t for a smartphone. This thing is more than just a PDA with built-in cell phone functions. It’s a PDA with a built-in cell phone. You can use the qwerty keyboard on the PDA to work on tasks requiring more processing power and screen size, and when you need a cell phone, just flip it over and pop-out the built-in cell phone tucked into the backside. The tiny phone runs on its own batteries and works as a basic cell phone (read: can only make and receive calls. If you ever wanted to ditch your bulky smartphone for a light-duty cell phone, then this patent app is for you (but, if you’re anything like us, the thought of leaving your smartphone behind never even crossed your mind)! It’s too bad this idea didn’t come up sooner – seeing as how the smartphone has obsoleted the PDA.
