Imagine that you come home from a long day at work, flop down in your favorite comfy chair and get handed a nice cold beer.  Sounds ideal right?  Only if you can afford the PR2 Robot which is a whopping $400,000!  But I'm sure it's worth it since it does more than just bring beer.  It can even cook pancakes and bake cookies!  That's pretty impressive right?  Not bad, but if it could wash the dishes, then it would be REALLY awesome.
