I am really interested in a 12 C lookalike. Had one on my TreoWX. I use all the functionality you mentioned except for the programming.

Dear Ed,Hi all; I'm the author of RpnCalcPro. It doesn't have the same layout as the HP12C (I intended to use it in portrait mode), but it has all the same functions except for programmability. It's $5 at present. More info at RpnCalc Pro
I've gotten some feedback from people asking that I make they layout exactly like an HP12 in landscape mode, so I'm working on it. It's a little tricky because an android screen is much smaller than a real HP12, so squeezing it all in is rather difficult. I have it working now for the Archos, and with a little tweaking, I can get it to fit on G1 and Droid. Look for the new layout soon.
Since I have a number of interested people here, I'd like to do a quick user survey:
Do you use the programming functionality of the HP12? I haven't seen a need to add it to the calculator app, but I might if there's a demand.
Do you find the HP12's n,i,PV,PMT,FV functions ambiguous? That is, do you have trouble knowing if the key will enter a value, or compute it? (I added a "Find" key to my calculator to remove the ambiguity, but maybe it's not needed.)
Also: the cash-flow calculations (Cf0, Cfi, etc.) Do you ever use these? Do you edit the stored values? Do you change the Ni values?
Other differences between the android app and the real thing: I have 20 memories, whereas I think the real one only has 10. The stack has 16 levels instead of 4. Statistics have their own registers rather than being stored in the main memory registers. I'm going to guess this doesn't cause anybody problems.
In general, I'm interested in whatever feedback you might have.

Dear Ed,
RpnCalcPro is just what I was looking for but unfortunately international users cannot buy stuff off the AndroidMarket. Only freely available software is shown to us. A work-around this that I've seen (for instance for SplashData's SplashId password manager) is to buy it directly from the authors and then download the .apk from them.
Do you have any plans to providing RpnCalcPro this way?
Thank you,
Thumbs up for the RPC Calc Pro. Not as good as the iphone app I played with on a friend's phone, but well worth the $5 and the best option right now on Android.
This link will take you to HP calculator apps for the iPhone. Having recently seen a friend's 3Gs using the 12c, it's as close to perfect as you can get outside the calculator itself.
I need to put in a vote for the CF0 CFi functions. I use them alot on my 12C. I have used the 12C from Lygea on my WinMo phone for years. Lygea is able to fit the full functionality of the 12C on a smartphone screen in both portrait and landscape. You may be able to gain inspiration from their layout.

Hi all; just a quick update. The latest version looks as close to an HP12 as I could make it. It's not programmable, so many of the functions don't do anything, but I've left the labels on for now.
This weekend, I'll be putting up a version with an improved appearance, especially on Droid.
I've been surveying my users, and NOBODY has said they program their hp12, so it looks like I won't be adding programmability to RpnCalcPro any time soon.

I never heard of Lygea before; I'll take a look and see if their screenshots give me any inspiration. I've been using RpnCalcPro a lot, and haven't had much trouble hitting the buttons, so I'll probably leave things as they are. I experimented with scrolling layouts to have bigger buttons, and found them nearly unusable. You really do need to have all the buttons on the screen together.
