I'm wondering if I might be able to get my hands on a portable model as well. Imagine how quick you'd get through queues if you surreptitiously pointed that baby at somebody's back and fired away... They'd be physically unable to remain in queue and the next venti' latte at Starbucks would be yours, in 10 seconds flat!!!

Also would work well at sporting events. I almost pity the next New York Yankee fan I see.... nah... let the bastards suffer!
