Just wondering what you guys think are really killer Mac accessories. What I mean by this is: something that complements and extends your Mac in a (somewhat) unique way, an item that fits with it aesthetically and works well with the Mac. Companies like MacAlly , XtremeMac , iSkin, and Griffin Technology come to mind. Also, the JBL Creature speakers seem to fit. I know there's a plethora of them but sometimes its hard to find the smaller companies all one one site.
