(I have killed three macbooks)
Not only that I've seen a magsafe connector on fire.
But other than that, it's supposed to be a breakaway, right? So if my laptop is sitting on the table and I trip on the cord, the cord unplugs. But that's never happened to me. If you pull the cable straight out (like if it's wrapped around your leg and you pull your leg away), the cord will stay connected and will easily pull the laptop off the table. I don't know if it was designed for heavier laptops or what, but Magsafe has never broken away for me when the cable is pulled straight out.
The only time it works as intended is if I step on the cable and it pulls the cable down, or if my leg hits the connector and it pushes straight up.
The main problem I see with the removal of MagSafe is that you will run out of ports while charging. Sure, I could buy the umpteen dock/hub/whatever, I guess...
