Griffin Technology is one of the more interesting Mac accessory makers. They always have original ideas and refreshing take on things. I love this new concept gizmo they have just announced – Twenty. Essentially plug in Airport Express and attach your old hi-fi speakers and have music streaming from your iPhone, iPad or whatever. It is simple and basic. Yeah, I know it is not very powerful – only 20 watts per channel, but I could re-use my old Paradigm bookshelf’s in my office. The tough part is waiting for it!
