I have a 42S emulator running on my iPhone, but it really isn't the same as being able to press physical keys on a hardware device.
One of the charms of these devices was that they were built to last. ie: the keys were injection molded with two colors of plastic so they wouldn't wear down. So, while I still have a couple of working HP's from the 80's, I've been through a dozen or more mobile phones in about the same time...

- lmilcin 7y agoI have actual 42S. The physical device lasts very well but the LCD fades out as it gets older. Right now mine does not have enough contrast to read it looking at it directly. You need to look it from downward angle and in perfect light. Other than that this is the best calculator ever made.
- mschaef 7y agoAt the time I bought my 48SX, I remember briefly considering a 42S. I had a lot of fun with the 48, but in retrospect, I'd have gotten more use out of the 42. (But what I really regret is not having bought a 16C.)
