At its original $180, Sphero’s R2-D2 droid was something for Star Wars fans to drool over, but probably not buy. But at $80? It’s the droid you’re looking for.
You can make R2 run around your desk with a virtual joystick on a phone app, but more importantly, you can make him emote. Even its included charging cable matches the copper color of the power couplings on his feet.
