The beauty of the MagSafe connector was that Apple had found precisely the right balance between attachment and detachment. Strong enough to hold the connector in place, weak enough to detach if it gets yanked.
The MagSafe 2 connector fails that balance test. Badly. The magnet is too weak. It’s so weak, it keeps falling out. It falls out if you brush it. It falls out if you tip the laptop slightly. It falls out if you look at it funny. It’s a huge, huge pain.
Like many others, I haven’t had this issue. While I keep the Air’s included MagSafe 2 charger in my bag for emergencies (and use the adapter at my desk), I haven’t had any issue when using it at airports and during travel.
I do appreciate that Pogue is being nitpicky — he really should be — I wish he had tried a replacement first, just in case his unit was faulty in some way. Also, we don’t know if it’s the MagSafe 2 or the computer itself.
