I'm still setting mine up, but one thing I'm not liking is the lack of the power cord extender which used to be shipped with laptops. So the charger cable is not long enough anymore for where I use the MBP. Now I have to pay Apple an absurd £19 for a short piece of mains cable with a plug on the end which must cost all of 10p to manufacture. The dongle thing I can live with because it's justified by moving forward, but the cheapskate omitted charger extender crosses the line.
