That would have been too good to be true, haven't even thought about that! I remember way back I was trying to make a cheap wifi-powered box with a display that could play short video's and stuff. The base idea came from https://www.youtube.com/watch?v=Ywr0A2aC_Jk https://www.youtube.com/watch?v=Ywr0A2aC_Jk, and I'd use a very cheap 3g-wifi router running openwrt as base. But in the end the firmware changed and made it impossible. But nowadays with an arduino mini pro, i2c, cheap small displays or audio modules you can get a long way! It does however require you to purchase a lot of stuff like resistors, opamps, breadboards.. etc. And in theory, with the ESP8266-module you could make any device internet-connected.
