Our BlackBerry-addicted friend Joanna Stern over at Laptop Mag sent me an email yesterday letting us know she posted a video of her experiences with the Xtensor.

What's the Xtensor you ask? Well, for $39.95 it's an exercise thingermajig designed to strengthen your hands and provide relief from symptoms such as those caused by too much BlackBerrying! I'm not sure why, but everytime I look at this thing visions of Freddy Krueger pop into my head. Be sure to check out Joanna's video... I love how she turns on some Jock Jams to do her "workout".

Oh, and if $39.95 seems a bit steep, do as Ronen suggests and check out the Gripmaster for $12.
