Quickie gripe. I have at least a half dozen devices that take three AAA batteries. THREE. What genius engineer thought that up? When's the last time you saw a 3-pack of triple A's for sale? I'm convinced these people are in bed with Duracell and Energizer. Think about it...what better way to get an instant 33% jump in sales than force unorganized folks like myself to by four batteries for a three battery device? Because I can guarantee you that "odd man out" 4th battery will be totally and completely MIA by the time I need new ones. And off I'll go to get another 4 pack. Bastages! :)
