What would you like to see in a future HP Prime II? (HP Prime², HP Prime 2X)

[Antonide]

Colour e-ink display on each key. This would allow for infinitely customisable key configurations. Maybe even reduce the number of keys required. Perhaps turn the areas surrounding the keys into an e-ink display. Although this would be far more challenging to implement and probably overkill.

Turn the back into a large e-ink display, or have a clamshell design, for handwriting notes, equations, and editing code more efficiently.

Speech recognition for dictating notes, equations, etc.

Camera with OCR to load equations/text from printed/displayed material.

WiFi connection for integration with a cloud service giving seamless. access to vastly greater storage and processing power.

Bluetooth for connecting to external keyboards/mice/speakers/headphones/data collection.

Of course this would end up with a calculator that would be completely unsuitable for school exams unless a seriously locked down exam mode could be implemented.

And arguably too close to a smart phone for people to consider purchasing in addition to their phone.

User configurable e-ink display keys would be enough to get me seriously interested.
