HP Prime micro sd

[matthiaspaul]

Either way, missing SDSC/SDHC card support remains an often mentioned downside of the Prime. It might make sense to limit data exchange capabilities on a device targetted for schools/pupils, but at the same time it makes the device less attractive for more advanced users, be it for "off-line" backup and "longtime" storage/logging, for storage of extra-large data items, or for easier data exchange with other devices without a need for USB.

Actually, I'm hoping for something like a "Prime Pro" in a number of years with added features:

* SDSC/SDHC card with FAT12/FAT16/FAT32 support
* optional capability to use standard AA or AAA batteries/NiMH rechargeables. Available capacity of standard batteries will significantly increase over the years, whereas proprietary Lithium-Ion battery packs will be impossible to obtain new in five to ten years.
* built-in beeper
* selectable much larger display fonts
* userRPL
* direct support for turns (360° = 2*pi rad = 400 gon = 1 turn) as a fourth angular mode (not only as a unit) in addition to degrees/radians/gons
* support for integer and floating-point numbers in any base 2 to 16
* support for special functions for computer scientists/programmers (including but not limited to all functions of the HP-16C)
* (even in decimal mode) optional number entry in binary E-notation (on double-press of EE or by using "B" for *2^ instead of "E" for *10^) and toggle display (single press of button) between decimal and binary scientific / engineering notation for easy ad-hoc conversion between SI and IEC prefixes (not only as unit prefixes, but for any displayed numbers)
* exponent shifting in scientific notation (+/-1) as well as in decimal (+/-3) and binary (+/-10) engineering notation
* full set of trigonometric / hyperbolic functions (as suggested in old thread)
* more detail-refined UI (as suggested in old thread)
* support for some kind of ASCII-based TIO codes to use instead of Unicode in source code (in order to "enter" Unicode characters on platforms not supporting them). At the minimum something like \nnnnn, where nnnnn is the code point of the Unicode character.
* bug-free operating system
