Barbie’s new role was chosen through a contest Mattel created this year that let consumers pick what Barbie’s next job would be. Computer Engineer Barbie won the popular vote, while girls selected news anchor as Barbie doll’s next career (what’s wrong with blogger, girls?). Computer Engineer Barbie will go on sale sometime this winter. That’s a binary code patterned T-shirt she’s wearing, and a smartphone, Bluetooth headset and laptop bag she’s toting. But my question is, does Barbie use a Mac or a PC?
