It seems as if the tech industry is infected with a gloss-over-function disease. Vista looks better than it works; Leopard, too. And the makers of all three of the 802.11n routers I tested in this mini-roundup poured a good deal of effort into outward aesthetics. Unfortunately, in the case of the Belkin N1 Vision, more resources were spent on looks than on making the device competitive. Belkin needs to work on the N1 Vision's performance.
