I find it a little amusing that people think a little trail of water running from the bottom of the mirror is a problem. We drive them in mud, over rocks and right into brush on the sides of trails but a little water running down the door after you wash it is bad....

 

I think it has to do more with water potentially and continually leaking into the door itself and rotting over time, but then again I don't even have a JK yet so I may be wrong.
However on the occasion that one might wash there muddy Jeep and even wax it to add a bit more protection to there paint, it may just suck to have a stream of water run down the Jeep 2 minutes after drying it. One hour may be acceptable but 2 minutes is like getting a sarcastic "Ha Ha" from your JK.
Or maybe your JK is saying, "Ha Ha, you think you can clean me, I want more Mud!!... Wooo Whoooo!"

 

Not sure about the '11 models but Rubicon's have had optional power windows and locks it's not been an included feature. I have seen plenty of Rubicons without unnecessary power equipment. When I bought mine in September I looked at another Wrangler which was a white 2 door hardtop Rubi that was all manual it was a Rubicon with one option, the hard top, and the sticker was just under $30K.
