I've got a MacBook Pro 15" Late 2011 that I'd like to trade for a MacBook Pro 17" Late 2011. I need a ViDock... Do you think that anyone would accept an even trade with no money involved. Would anyone accept a trade of the MBP2011+MB2007? Would anyone accept a trade of the MBP2011+M11x? Would anyone accept a trade of the MBP2011+M11x+MB2007?
