I'm honestly for pretty much all kinds of chrome. They always seem so CP to me.
This is probably taking it too far, but if there were different size and one of them could hold a gun to pass a weapons inspecting machine that would be fucking awesome. Pulling a gun out of your fake leg and blasting a choomba in a safe room.
Might be hard to balance, but a boy can dream!
But anyway -- maybe a cheaper 'pocket' kind of chrome where you can stuff chy in your arm or leg that's literally a doc just carving into you and installing a small container as well as a high-end implant for rich folks (or flashy mixers) that lets you insert your credchip and access your bank account and shift funds around, send transfers, etc. without having to access an ATM like some sad junior.
In terms of money though I definitely far prefer the idea of the implanted credchip. That sounds like a must have in any corporate/fixer arsenal. Only obstacle I can see here is what happens to the chrome if it is stolen? Does it stay locked to the same account or switch to the new owners account? If it stays on the same account is it really worth the convenience of the chrome if someone stealing it can then drain your entire bank account?
