Pros :
Follow you around to shoot video of you so you don't have to keep asking your friend
Carry stuff for you
Looks safer than the other thing that Mike Tyson fell off and hit his head. I know someone got a concussion from that. Maybe not from this though

Cons:
Attract a lot of unwanted attention on the street
Styled like a toy for a 5 year old child. How about a robot that looks sophisticated and sharp. Sexy curves or something. More Iike the racecars
