why in the fuck would you make an ethernet and wifi shield for arduino..... which has a 400mhz cpu and 64mb ram running linux .....

why keep the arduino

case in point: i am now using a dragino yun shield completely devoid of the arduino board without problems

and it comes with python already installed in it??? sure without the arduino i lose the digital and analog pins (which im sure could've been implemented otherwise) but all i need is the serial connection to talk to a thermal printer
