CES is going on right now in Las Vegas and Sony had something pretty cool to unveil. Aibo, the robot dog. If you’ve never had a dog or you’re not a big fan of picking up poop this might just be the perfect pet for you. Aibo responds to voice commands, head pats and even wags his little tail. Now, just in case you want to buy one of these for yourself you should know that Aibo isn’t cheap. There is a presale in Japan right now and they cost about $1,750. A bit pricey but at least he wont poop in the house.
