Simultaneously with Radio Shack deciding to liquidate their line of Vex robotic poducts less than a year after they were introduced, the Mythbusters team review it positively.
Although much more of a Erector-set style construction kit than a rapid ubiquitous user experience sketching tool, it's clearly from the same universe of ideas, as Grant Imahara, one of the MB team puts it (in copy that's going to end up on a box soon, I'm sure):
With the VEX System, it’s not like you’re sacrificing a lot of time and energy just to try an idea. It’s quick and easy, and it promotes discovery through trial and error, which is what engineering is all about.
(tangentially, who names a potentially frustrating product "vex"--c'mon, marketing department!)
