I totally agree. Here's the Packbot from iRobot who make Roomba: http://www.irobot.com/gi/ground/510_PackBot http://www.irobot.com/gi/ground/510_PackBot They're slow. The full military version is $120K but simple versions are half that. Another analogy is the Firstlook: http://www.irobot.com/gi/ground/110_FirstLook/ http://www.irobot.com/gi/ground/110_FirstLook/ (There's a nice video).

The article is sensationalist by not saying that.
