I bought mine over 15 years ago while enrolled in an MBA program and still use it regularly. I can do NPV, IRR, and FV calculations before my colleagues have even fired-up their notepad computers.

Not nostalgic for me either! I use one every day at work, as most commercial real estate appraisers do.

I got through engineering University with a 15C and had it for many years until it finally died. I figured I’d just buy a used one on Ebay until I saw the prices and nearly fell off my chair. I wound up buying a 48GX (like smokeandoakum), and while it’s still reverse polish, it just isn’t the same — it’s big and clunky and full of a zillion features I don’t need. The 15C was king …

I also had a 16C which was a special programmers’ model. It was almost completely bereft of other functions though … great for assembly language programmers, but not much else. Well taht one I subsequently sold on Ebay for @200. Sweet.

@ted – because the notation was introduced by a Polish mathematician. For more info, do a Wikipedia search on “reverse polish”.

If it’s not a 15C, it’s just a toy.

Despite its popularity, I never knew anyone that had the 12C. I had the 16C computer science model (I lost it in college in the late 80s when I left my backpack in class), and most of my friends 11 or 15.

I still have and use the HP-11 scientific model I bought through a friend who works for HP. Cost me $99, if I recall correctly (probably 1986?). It is badly dented, but it works great.

I’ve got the 48-gx which is the best calc ever made. (at least for engineers.)

No nostalgia here – I still use my hp 12c platinum, and I’m in my 20′s.

I loved that thing. No one wanted to borrow it.
