12C Platinum REVIEW, with comparisons to 48GX, 50g & Prime

[JDW]

A friend from the US shipped his 12C Platinum to me in Japan for the purpose of my doing a video review. I was a bit concerned that my being an EE and not owning any of the Voyager series might negatively impact what I present, but I think the info I put in my video can be useful since I compared the 12C with my existing HP calculator collection.
