Okay, at the risk of being eviscerated (and not directed specifically at you, maclaw21, but rather open for discussion to everyone who has commented on the lack of MagSafe), when was the last time your Macbook was really in danger of the power-cord-stuck-to-the-computer-when-someone-walks-by-thereby-pulling-the-machine-off-the-table accident? Seriously.
For some (few), this is a legitimate risk, and for them, there is an adapter. But, I would put my money on the fact that, for the vast majority of us, our computers are no longer at real risk for an accident via a hard-connected power cable.
Now, I'm open to being wrong about this. Discuss amongst yourselves.
