I also get tired of lamely designing things so only the shuttle can do it...
The whole ISS project was a big pork barrel aerospace project from the beginning meant to justify the shuttle by having something that only the shutlle could do. The stupidity of the self fulfilling requirements makes me mad to this day. Then the irony is that the shuttle hasn't been up to the task to do something that should've never been designed in the first place. But we keep throwing good money after bad, ad infinitim.
