" Somewhat of a cross between Richard Simmons and an iPod, Philips&amp;#039; Activa MP3 player goes straight for the cardio crowd. The hook: The player detects how hard you&amp;#039;re working out, and adjusts the music accordingly. Run faster and you&amp;#039;ll get an up-tempo track. Slack off and you&amp;#039;ll hear something slower--in addition to preloaded &amp;quot;words of encouragement&amp;quot; designed to keep you moving. Weird. The Activa MP3 player comes out in April for $130. "^^<http://www.w3.org/2001/XMLSchema#string>
