Just got myself one of those blue toys. It's very blue. It's pretty different from the older days calculators like the 41CX and 42S, but everyone who saw it, liked it. The keys also feel softer. One of my students who has a black 50G also noticed the softer key feel. The battery cover is loose, so I changed it with a black cover, which fits pretty snug. Maybe just coincidence. I got it from Spain, obviously, since it is only available there. It's a nice variation from the black, for those who want change. One thing I am concerned about is because of the lighter blue the body is in, it may tend to get 'dirty' easier. The black ones would probably hide these flaws, but the blue would show it up. Just my observations.
