I like my gadgets to be colored differently from the normal grey and black and I needed a scientific calculator to grade statistics papers, so I bought this one for cheap.  I don't know what I can say - it's a great scientific calculator.  Has all of the functions that are necessary for me - sine, cosine, tangent; fraction to decimal; probability functions; several statistical functions (to the point that we don't actually allow this calculator on our statistics exams; it solves the mean, standard deviation and variance for a list of variables) and others.  There's a little card inside the cover that tells you how to perform these functions.  And it's pink!  I'm the only one with a pink calculator so I know it won't disappear.
