Yeah, I would consider retiring my Air for one of the new Pros, but I'll have to spend ~$300 replacing power cords (home, office, backpack), monitor adapters (backpack, around office, at home), while still having to keep the old chargers and adapters due to my old work computer. That dissuades me.

At the office - this now means that the conference room adapters, power cords, etc will have to be swapped out as soon as a new employee starts.
