Beware not to buy HP Prime, if you are engineer!

I attach here my opinion

I am a chemical engineer working as process engineer in an engineering company.
I currently use a 50g, but tested also the Prime emulator to understand if it fits my needs.

What i require from my calculator?
1) excellent Units of measure handling (conversion, arithmetic operations, etc.)
2) numeric solver capabilities for single equations and systems, even with units of measure
3) capability of using long names for variables and programs
4) capability of using directories
5) pc connectivity or sd card

1 and 2 are non-negotiable features and both missing from Prime.
Furthermore i found the multiple environments of the Prime and the predefined variables names/types quite annoying.
Basically i found the Prime as shipped out-of-the-box, compared to the 48-49-50 series, does not fit my needs for my (repeat: MY) engineering work.

What would be the _perfect_ calculator for me and my job? The 48 series with lot of internal memory, SD card and USB. Graphic capabilities can be stripped away.
Waiting for Swissmicros..... :-)

My two cents....
