Just received my new HP Prime Graphing Calculator!

I've been fiddling with it, figuring out how it works.  It does so much that it is going to take a while to figure out.   I like the touch interface (which seems well integrated) and the programming language (somewhere between Basic and Modula-2).  Very cool!

I suspect the cuts at HP are affecting their Calculator division; there are no user manuals to download on their regular support site.  Hopefully they will figure that out soon.

The only difference between a man and a boy is the cost of the toys!  

I remember the HP programmable calculator which had strips of some kind that you used to input the program you wanted.  1973
I think the 70s version cost $500.  Has the price changed?
+Jonathan Cameron what you use it for? on the field? i myself haven't used calc for a decade... because i just go to emacs or Mathematica or any lang's interactive command line instead.
Gave up my 48s for emulators on my smartphone.
+ErgoEmacs I loved my old HP calculators (HP-67 and 28S) and it's fun to have a new one.  I have not used calculators much in the last 20 years except to do quick calculations, scale things, check vector magnitudes, etc.   Like you, if I need to do anything heavy duty, I use use Python, Mathematica, or recently Matlab.  I've also played around with Sage recently which has promise but is a bit clunky.  

What brought on this purchase was that I had to replace my simple HP solar calculator (that I used for quick calculations) because its display was going out.  I got an HP 35s and was disappointed in its limitations (fixed 4-level stack, a buggy ROM that has not been updated since its introduction more than 6 years ago, etc.)  So I looked at getting a 50g but heard there was a new one coming out.  So I limped along with my Android Droid48 app and my HP 35s (mostly the former) until I could get this new calculator. 

So what will I do with it?   Grossly under-use it most likely!  But I also hope to learn how to use it in more detail.  I'll probably write some programs to simplify certain calculations that I have to do from time to time such as compute quaternions for certain typical rotations.  But I'm sure that mostly I'll do those same simple calculations that I was doing with a much simpler calculator!
+Kathy Johnstone The price was about $120 which is inexpensive for a top-of-the-line HP calculator.  But when I added in CA tax, shipping, etc, it was close to $150.
+Matthew Gregg I found the Droid48 on my Android table to be reasonable, but a little frustrating because there is no tactile feedback from the "keys".  It was also not very visually appealing.  I did not try any of the HP calculators apps that you have to pay for; perhaps they are better.  What did you switch to?    It is not hard to imagine an app that has basic calculator functions merged with Python as its programming language.  With all the Python libraries available, you could do almost anything!
Technology has certainly come down in price, unlike most things.  Our first computer, two double sided, double density 5 1/4 drives, with a CPM operating system, cost $5,000.  We waited 3 weeks to get the double sided double density drives.  They were a miracle!  We didn't think DOS would make it because it was so expensive!
I have Droid48 installed for fun, but my daily use app is Free42 by Thomas Okken. It's fast, easy to use, and free - highly recommended!
