I adored my HP Veer, I bet that if I get a working one in my hands I’ll blind-type flawless again in seconds, I was better on that thing than any full size keyboard. Best phone I’ve ever had because of the keyboard and the ease of customization when you know Javascript. Screen was a bit too small (I consider every modern phone way, way too big) and speed could’ve been better but wasn’t bad.

I don’t know for sure but I think it’s the current, higher voltage will bridge a bigger gap/higher resistance but a human body doesn’t have that high of a resistance and car batteries are capable of providing plenty of current (I think?)
