I'm glad glad glad the magsafe connector is gone. Every single one I've had has gone flaky at the magnetic connector, such that you have to fiddle with it to get just the right alignment for it to charge.

The one thing I'll miss is you don't really need to aim a magsafe connector, just bring it around the slot and it'll jump in. Not a huge gain though, and probably offset by the ability to plug power on the right side, not have to snake around to the left.
But for me, the worst bit of hardware Apple has ever made is the MagSafe-to-MagSafe 2 adapter. _That_ is where the flakiness happens for me. If I'm plugging "native" plugs straight in, never a problem, but that darn little adapter — that can sometimes be 10 minutes of my morning getting it to connect.
However, in 4.5 years. I've only had 1 connector fray at the tip and ultimately fail. The second one I bought, has lasted for 18 months now and is doing just fine with very careful use.
Still, that said. Magsafe has saved my laptop a whole bunch of times. I'd rather have a laptop with it, then without it.
That's kind of a standard feature all around.
Moving to a standardised non-proprietary charging interface is a move ahead.
