The $6,800 TAG Heuer smartphone: High-end watchmaker TAG Heuer has introduced the Link phone, which has a rather astonishing price tag, runs Android, and comes with a “paltry” 256MB of memory. (Check out the promotional video.) Buyers can customize their phones’ cases in a variety of materials, from rose gold to titanium, just as they would a TAG watch. They can even add Calfskin-leather trim, or a sprinkling of diamonds, for good measure.
