Robot Heart Surgeon

OK, there are new, cool things happening all the time.  Scientists slow light down until it goes backwards, for example.  But this is definitely futuristic.  A robot in Italy (monitored by a PC in Boston) performed surgery on a heart patient.  Yes, the machine repaired the human.  This is a turning point in robo-human relations.

So the question is which robot would you want to operate on you?  CP3O might have a good bedside manner, but R2D2 is more discrete.  Robbie the Robot seems like he'd panic, where the Terminator is calm under pressure.
