Perhaps I can trade an Hp48G case for that sorry excuse of a leatherette case you got with your Hp ( I am joking, you are better off with THAT case).
I feel the new case is a BIG improvement over the previous 48G line case. Even with a streamlined case, it is still a big bulky graphics calculator, so you might as well protect it with a good case. The older Hp48G case was not much more than a slip cover.
My day to rant!!!!
I use an Hp48Gx on my desk. Is it my favorite? No, my Hp42s or Hp 15c are my favorites (depending upon my mood or needs). But to sit on my desk at work, the Hp48G series has lots of features that save me reference time or provide an easy solution to an otherwise tough problem. But I sure hate their bulk and prefer the simplicity and size of the smaller, yet powerful pocket calculator (if the Hp 42s where even 1 cm shorter, my Hp 15c wouldn't even be mentioned, although it is also tough to give up that layout, once you are used to it).
I would agree with your assessment of the Hp33s case, as IT IS SUPPOSED to be a pocket calculator and the case makes it NOT SO!
