If there's one thing I wish for all laptop power supplies, it's that they would license from Apple (or work around, patent-wise) the magnet attachment system that makes cable--tripping far less dangerous to man or beast, compared to a few years ago.
Also just wear and tear on the connector. I've seen laptops become unusable just because the power socket is stupidly designed and ends up getting loose. Even some sort of less-patented snap design or something would be better. Van der Waals force, I dunno. Hell, even just something that isn't a cylinder that goes over a small bendable pin, maybe something totally solid like the Apple one only it goes in further, that would be nice...
