Vangelus, Megatron already said why he keeps Starscream around. Yes, you are right about the process of thinking. Keep in mind, however, that Starscream in this iteration has a vast intelligence network. If you have watched Gungrave, then you know about how intelligence networks break down when the person coordinating them is dead. He alone knows where many Decepticon cells are at that even Megatron himself does not know about. This is why. It was explained to Airachnid before she betrayed Starscream and that is why Megatron was pissed at her. Dreadwing was just a generic loyal soldier to Megatron. He is a dime a dozen to him. Starscream actually has made himself valuable to Megatron which is why he puts up with his insubordination. I do not know if this changes your mind about this. It made perfect sense to me when watching the show. The Forge of Solus Prime can only make items that Optimus has some familiarity with. He cannot create phase shifters and other relics because he does not have the no how to do it. Optimus' Space Bridge knowledge could of been easily supplied by Ratchet. The Forge of Solus Prime is not like Forge from X-Men. Sorry, I am seeing some flaws with many of the arguments. I am presenting what the fiction has stated about the limitations of the Forge of Solus Prime. Gogdog, watch Legend of the Galactic Heroes for flawless story telling. Trust me after you watch it, all other fiction will never be the same again. I do not know, I might be to forgiving with Prime. I do not think so. I tend to pride myself on having a critical taste. Prime has done nothing to offend me as much as all of you have said it has to you. At most, I would predicate my complaints as nit-picks.
