My Kensington Pocket Mouse broke the other day, so tonight I sat down to order one of those Logitech Nano mice. I wanted the tiny USB receiver so I could put it in my notebook computer and leave it there, without worrying about breaking it off when I move around. But I learned that the mice are not full-sized. For some reason neither Kensington nor Logitech puts mouse dimensions on their web site, but I was able to find some reviewers who had measured the things. The Logitech Nano 550 is bigger than my Kensington mouse was, but I want full size. Googling for “full-size mouse nano receiver” tells me I’m not the only one. So I’ve put my credit card away. For now I’ll just drag my corded optical mouse around with my computer, and wait for Kensington or Logitech or somebody to come out with what I want.
