I've never really paid attention before, but I notice these Kensington powerbrick devices that are supposed to replace the AC adapter that comes with your notebook. They are of course slimmer and supposedly provide better/cleaner power (I think that's what the label said). Anyway, I'd like a more conventient power supply. Are these "universal" adapters they sell at computer stores usable with the macbook pro and it's magsafe adapter? I know they have them with high enough wattage, just wasn't sure if I could make it work with the macbook pro.
