I still have mine from 1987. You can still buy the HP-15C Collector's Edition new, but it isn't as good as the originals with their perfect keyboards and the silicon on sapphire technology that gave them their incredible battery life. The SwissMicros DM-15L is also a worthwhile substitute.

I got my DM16L two weeks ago and I love it to bits!

They even upgraded it to USB-C (even though the product description still says Mini USB), which was a pleasant surprise. I only just got into RPN calculators (and programmable calculators in the first place) a month ago, loving it so far.

I got the HP15C Collector's Edition, because I always lusted after those HP calcs, and never could afford one. People in this thread asking: why? Well, many of the calculators on screen are simply worse, or copies of decent calculators but you have to press every button with the freaking mouse. A dedicated calculator feels nicer. Copy&paste is nice with an on-screen calc, I admit.

I do have a few other calculators as well, so I'm definitely biased.

Yea, I’ve felt the new 15Cs and they just aren’t the same. Shame. I might have to give SwissMicros a try.

There's a really good emulator for the iPhone! Back when I bought it, it came from HP themselves, but a few years ago they sold it to another company which actually maintains it. They just released a major new version a few weeks ago.

Yes, the new version is really nice now in portrait mode. Nice app. Now if only we could have tactile buttons...

I have that and do like it even though it lacks that HP tactile feel.
