In June 2010, v4.0 launched with faster speeds, tighter security, and lower energy output.

Touted as the world's first GPS fitness tracker and smart MP3 player, the Motorola MotoActv watch tracks your stats while you run, bike, or golf. It syncs all the data online and even suggest music to workout to. (Available now, $249.99).
