I don't miss it. I prefer the "T".
It sticks straight out, so less risk of getting in the way of the ports next to it. That is my biggest pet peeve with the "L" style cord.
When it sticks out the back, most people tend to have the cord wind around the back of the unit ... right past the exhaust for the cooling fans. The prolonged exposure to the heat from that exhaust is going to do bad things to the insulation on the power cord ... make the cord brittle, for example (in extreme cases), to the point where it cracks, exposing the wires inside.
There's lots of people that have had this problem with the "L" style cords. I suspect it has something to do with Apple's decision to switch back to the "T" style with the Magsafe2 chargers.
