Questions on HP Prime and its features

[frontier]

I've had the 49g+ for years and love it, but it's starting to fade. Old age. I'm thinking of the Prime. Two features that I must have, and that were on the 49g+, are the Equation Library (which comes with built-in engineering equations and drawings) and Units (that allows you to do unit conversions). Does the Prime come with these? It's not clear from a scan of the User's Manual.



Also, unless I'm missing something, when I'm in HP's website and search for the Prime, it's not available. That also goes for hpshopping.com. It shows several other calculators, but not the Prime (or any other graphing calculators). It seems to be available on Amazon, eBay and elsewhere, but not from HP. How can that be?



Thanks in advance for any info......
