If you consider iPhone too advanced to use, then you may consider its newest competitor ARRRPhone or rPhone. It is designed to give the user a nostalgic feeling of rotary keypad sans screen, play music via the dedicated music cylinders and needs steam to perform all these tasks. It also functions as a satellite phone with a retractable antenna to give you zero drop calls and a strong vibrasonic action. I would love to own this had it been for real…as a modern antique ofcourse.
