If a sorcerer could prepare some of his spells, he wouldn't have to apply metamagic on the fly and then suffer the augmented castin time penalty.
In 3.5, there was a feat that allow a sorcerer to prepare spells like a wizard (and then cast spells with metamagic at the norma lcasting time), it was called Arcane Preparation IIRC.
In Pathfinder, the only way to do such a thing is the Eldritch Heritage feat chain to get the Metamagic Adept power from the Arcane bloodline. You don't prepare your spells but it allows you to apply metamagic without increasing your casting time.
Why would you take EH: Arcane when you're already playing a Sorcerer, rather than just taking the bloodline?
