The phone is a moto hyper one. 4 or 5 years old, I fear the day i need to switch. Technically it has two sim cards slots. More precisely: one sim card slot and one slot that can be used either for sim or SD card. Since sd card is non-negotiable for me, it means one usable sim.

Audio jack yes, but not replaceable battery.

I haven’t tried vertical mouse. Maybe I ought…

No luck with the imgur link :( I’ll try again later

• Phone with dual sim card slots and a sdcard, plus pop-out camera (my present phone has all of that except the second simcard, and I refuse to replace this phone!) ** Charging port on top ** Slightly thicker to fit a larger battery - and possibly slightly better optics for the main camera.

• Computer mouse about 15% larger than the “large” mouses they presently sell.

• Detachable 10-key that’s mirrored for easy left hand use.

• In general, small electronic devices should have more than one button for interaction. It’s easier to remember 3 different buttons than 3 different Morse codes to achieve the three different functions.
