Yeah, but still... I mean, a cordless screwdriver is nice, but e.g. a cordless drill only makes sense if you are regularly going to drill 10 holes in different places all around the house - otherwise the time spent plugging in your tool is negligible compared to the time you will spend drilling the holes. Not to mention you have to make sure your batteries are charged. So they make sense for professionals, but not for regular "DIY people" who only use a drill once every few months...
