I'd like to see a designer speak up about using stuff like this more than one time. I find I'd hard to believe that you would sit down, after already playing around with this once, and say "this time I'm going to add a chevron to each cell, put the button on the left side, and go test it in the hallway". If your app is a table with a stock navigation system do you really ever need to build a second version of the same thing?

Every project/team is different. Sometimes a designer wants to communicate with another designer, sometimes with a developer and sometimes with a client. Each of these stakeholders will react differently to:

'...this screen looks like.. well you know a stock tableview'

And sometimes these people aren't in the same room/building/country

Simply dismissing the tool because you cant think of a use-case is a bit short sighted.

PS: also when designing for the iphone, elements have a surprisingly different feel when shown on a device.
