Yeah especially for developers there's never a need for the latest and greatest. For creative professional they never upgrade the os on a piece of hardware, that's another reaso they choose Macosx over Windows for things like making hit songs or doing movie editing or soundtracks. For creative professionals they need the latest hardware to test their entire setup with the next version of MacOsx. As developers its moree cost effective for us to buy these second hand systems from creative professionals doing their upgrade cycle than going brand new.
