Okay, as long it is not humans! I also own IRobot. The Military side probably will not grow much. The commercial side is where the growth is now. The Roomba's are selling like hotcakes. I have bought 5. One for my daughter, one for her mother-in-law, 2 for my bridge club and one for myself. They work great and as the population ages vacuuming is one task that can be automated. I like the CEO because he thinks in practical terms.
LOL - I just happened to fly by here. Also hold IRBT. It is the up and coming robotics play in commercial, military and medical. No threat to ISRG but it will be a significant player in their industry within 3 years.
