At midnight tonight, HyperMac will shutter shop and re-open as HyperJuice "in the coming weeks." This is, of course, due to Apple getting all legal on their use of patent-defying MagSafe connectors, but HyperMac is hopeful something can be arranged.
This is why we can't have nice (allegedly patent-infringing) things! After drawing legal heat from Apple for its MagSafe connectors, HyperMac has announced that they'll stop selling their MacBook charging cables and car chargers on November 2nd. But there's hope!
