They are not banks, nor regulated similarly, so more risk of losing money and not getting it back in trade for perceived convenience.

Amazingly, there is this nifty thing called a “port” that allows a mouse to be plugged into a laptop. It is pretty incredible technology. /s

I tend to vacillate myself depending on the noise of the environment vs the work at hand. If I need to spread out across a few monitors, dock it. If I just need to do some simple paperwork, portable. If I want to force no distractions, portable (as it is more difficult to see things when your screen real estate is reduced.)

Helps if you have good eyesight too, laptop UIs today are at clown magnification levels anymore.

A tale as old as time. The US nuclear missile codes were 000000, but it didn’t matter. The chain of command was purpose-built, ironically, so the front line soldier in a cold war scenario had to make the last decision to delete all life on the planet. Chain of command doesn’t matter at that point. You are choosing to kill everyone you know from an order from who knows who. The ultimate checksum.

You will always be better at decisions than an n-dimensional matrix of numbers on an overpriced GPU.
